Jailbreak 6.0.1 Untethered/Tethered iPhone & iPod Touch With Redsn0w

iOS 6.0.1 the firmware that was released today is already jailbreakable. Note that this jailbreak will have the same specifications as the previous one and only work for pre-A5 devices. In addition this jailbreak is still tethered for all devices other than old bootrom 3GS’s meaning that you will have to boot tethered every time your device shuts off.

Tethered
- iPhone 4
- iPhone 3GS new bootrom
- iPod Touch 4G
Untethered
- iPhone 3GS old bootrom [Does your device have an old bootrom?]

Tutorial for all A4 devices (Tethered)
  1. Download and Install RedSn0w 0.9.15B2 or higher. [Download Link]
  2. Download a copy of your device’s iOS 6.0 firmware. [Download Link]
  3. Invoke DFU mode on your device, if you don’t know how to do this RedSn0w will walk you through it when needed.
  4. Open Redsn0w, navigate to: Extras>Select IPSW and select your iOS 6.0 firmware that you downloaded in step 2.
  5. Now navigate back to the home page of RedSn0w and click the ‘Jailbreak’ button. Leave this to continue until boxes come up and check ‘Install Cydia’.
  6. Once done, your device will appear as if it has just booted. However Cydia will not be on your homepage. You now need to perform a tethered boot.
  7. Connect your device back up to your computer if you have disconnected it, and reopen RedSn0w if you closed it. Now place your device one again into DFU mode, and go to Extras>Select IPSW and select the same firmware that we did in the first step, it’s essentially the same process. Once RedSn0w has done it’s thing, select ‘Just Boot’ and when your device reloads it will have Cydia on it!
Since the jailbreak is tethered you will have to complete step 7 every time your device fully powers down.

5 Reasons Why Your New iPad (iPad 3) Runs Hotter Than Your iPad 2

A lot of people are talking about the proposed ‘heatgate‘ issues effecting the new iPad (iPad 3). In fact earlier today we told you that the new iPad ran about 10 degrees hotter than the iPad 2. Now although heatgate seems to be a hot topic right now, a lot of people are not talking about the reason why the new iPad becomes warm during prolonged use. It is not a design flaw like Antennagate, rather, the actual specs of the new iPad that contribute to the increased operating temperature.
New iPad (iPad 3) heatgate
As brought to light by 9to5Mac, CNET spoke with DisplayMate’s Raymond Soneira about just why the new iPad is a bit “toastier”…
  1. Twice the LEDs: That means more heat coming from more LEDs. This is especially a problem at full brightness.
  2. 2.5X the power needed: The brightness efficiency is lower, because the new iPad has more pixels (which means more transistors) compared to the iPad 2. More pixels and transistors take up more space, meaning less opportunity for light to pass. “So they basically have to blast light through the LCD to make it come out.” Soneira adds: “I measured the LED power at maximum brightness–it’s two and a half times greater than on the iPad 2.”
  3. Battery generates more juice: The battery has to push out more power. This makes the battery warmer.
  4. Traditional LCD technology: Sharp’s power-efficient IGZO technology was not ready for the new iPad, which forced Apple to use traditional —and less power efficient— amorphous silicon tech. [To be fair, the older iPads also used this tech. Perhaps Apple was hoping to go 100-percent IGZO to offset the above].
  5. Qualcomm LTE Chip: Although not officially mentioned by CNET, the new iPad’s 4G connectivity support, allowing for faster than home broadband speeds, increases the operating temperature during continuous use due to the strain on the battery.
When you consider what Apple packed into the new iPad it is nothing short of a miracle that they managed to keep the operating temperature at only about an increase of 10 degrees to previous generations.

The “New iPad”: Will it Keep Apple at the Head of the Pack?

After months of anticipation, gobs of fanfare and a good amount of leaks and speculation, the world now officially knows everything about the next generation iPad tablet computer from Apple (AAPL) that it didn't already, which can be boiled down to two words: not much.
The same can be said for the company's stock which was more or less flat as of the writing of this post. So what does it all mean for Apple going forward? Gone are the days when it took a few months for a product to actually go on sale after its splashy introduction to the world, which allowed for much greater period to speculate over demand. In short, you can no longer rely on that almost certain pop in Apple shares as excitement builds ahead of new products. In fact, analyst David Garrity of GVA Research suggests today's iPad product tweaks can effect other manufacturers as much, if not more, than Apple itself.
As for those tweaks and what they mean for those looking to buy (or not buy) the new device, most of the improvements in the lamely named "New iPad" were fully known in advance. They are not only largely incremental from the iPad 2, but also available in other products already on the market.
Still, one big improvement could make the new iPad just as sought after as its previous models: "The move to 4G LTE connectivity (faster internet) is going to mean a great deal in terms of this device supplanting other types of computing devices, whether it's desktops or laptops," Garrity says in the attached clip. He also says it will be interesting to see if the inclusion of 4G on the new model, as well as the reduced price on what he jokingly calls "the ancient iPad" will have much effect on enticing more commercial or enterprise users to adopt the technology.
Speaking of new technology, with the release of the new iPad speculation has already begun as to when the "iPhone 5" or the much talked about "iTV"might be rolled out.
"They may come out and call it the 'New iPhone,'" Garrity says in light of today's naming tweak of the iPad, adding that whatever name the smartphone eventually takes, it's something we can expect "by the end of June," with some update on Apple's TV offering coming in the second of half of the year.
What do you think of the new iPad? Are you moved enough to buy one or happy with what you've got?

Is it “iPad HD” Instead of iPad 3?

March 7 is not very far now. It’s five days at best and speculations of the name of the device that Apple is going to launch / release is already ripe. Well, for us, it’s still the iPad 3 but several indications have now surfaced which seem to think otherwise. iPad HDSome tweet leaked the inventory at Griffin’s which makes high-quality case covers for iPads and other iDevices. The listing shows three occurrences of what is termed as iPad HD (3). So is the iPad 3 really called “iPad HD”? Perhaps.griffin-ipad-hdAnother popular case cover manufacturer, Belkin, has also been reported to have named the iPad 3 as the iPad HD.
There is this application called Tapatalk for the iPad, BlackBerry and other devices, whose usage data has been depicted by Gizmodo. The report there points out to a small percentage of the usage coming from what’s termed “iPad HD.” tapatalk-ipad-usageOf course, the data pointers could be changed easily so there’s no concrete proof that the iPad 3 is actually named iPad HD. As regards nomenclature, there has always been this time of intense speculation in every iDevice’s pre-release time span. We had discussions about the iPhone, about the iPad when it first arrived, and about other iDevices too (for instance, iTV).
The iPad HD naming claim comes with a supportive stance though. The most prominent of iPad 3 featuresis the dual-LED backlit display offering a HD display that far exceeds the Retina Display on iPhones. Could this answer the “iPad HD” nomenclature?
Other awesome iPad 3 features that have been constantly rumored are the A6 processor, enhanced cameras and LTE connectivity (which is highly anticipated).
The March 7 iPad 3 release date seems to have caught up with the entire fraternity now. If the iPad 3 is launched then, when would be iPad 3 release date? We can speculate that a full-fledged release might happen in mid-April or May depending on the demand and the supply chain segment.
Anyway, let’s all wait for the huge happening that will settle the name – iPad 3 or iPad HD!

tutorial : iPhone Home Button Not Working? – How to Fix It?

iPhone home button not working? Well, don’t worry. Quite a lot of people have the very same problem. Something seems to go wrong and both the single and the double-click functionality of the home button seems to be totally lost. When this happens first, one is easily prompted to press harder. Sometimes people just thing it’s the hardware problem and that the home button is gone for good. This may not be the case most of the times.
The problem might occur because of two reasons – one, the software may be faulty and two – this is the worst case scenario – the hardware might be faulty. If it is the latter, you definitely need to go to the Apple Center and get a new iPhone. If the problem is with the software – which it mostly is – one needs to try out the following methods.
A problem with the software usually is set right when you do a restoration of the iPhone OS. You can either do a restore from the backup, or do a complete restore in case you have not much data to worry about. Restoring from the backup or from scratch lets you reconfigure all your software settings so that whatever it is that was bugging the home button on the iPhone would go away.
However, some people have reported that both the types of restore does not bring the intended results. In that case, you’ll need to follow some other method. Here’s one more method which seems to work in favor of some iPhones. You could try it too.
  1. Open any application on the iPhone
  2. Press and hold the Power button till the ‘Slide to Shutdown’ screen appears.
  3. Now release the Power button and gently hold the Home button.
  4. In all probability, your Home button would start functioning normally again!
In the case that it fails to do so even after all this, you’ll definitely need to check out the hardware part. If you have just recently bought the device, then you get a replacement warranty so you can make use of that to get a new device quickly.
Update
In case your iPhone home button has become less sensitive or is even broken, iOS 5 has come up with the great solution named ‘AssistiveTouch’ feature. Assistive Touch is one of the accessibility features in iOS 5 that can be served as a workaround, if your iPhone home button is broken.
How to Enable Assistive Touch to Access Home Button from Screen in iOS 5:
Got to Settings -> General -> Accessibility. Scroll down to bottom and tap on “AssistiveTouch” option. Set it ON to activate the option.

After setting AssistiveTouch to ON, you will see a transparent round button at the bottom right of the screen. Tap on that round button to bring the touch menu.

You will find the Home button option that works just like as the physical home button.

Hope, latest iOS 5 AssistiveTouch feature will bring the intended results.

iPhone 5 Pictures

Is June Going to see the iPhone 5 Release Date?

Recent reports indicate that the iPhone 5 release dateis going to be in June of this year. Foxconn, the manufacturer which produces Apple products, has confirmed that the iPhone 5 production is on its way. Going by Apple’s typical six month turnaround the iPhone launch would be somewhere in June or July.

There have been sample devices but it hasn’t yet been confirmed which will be the final one as all of them have few common things that make it difficult to judge:
  • 4+ inch display (made by LG on at least one of them).
  • No teardrop-shaped devices, as rumored in the lead up to the iPhone 4S. Samples so far have been symmetrical in thickness (also longer/wider).
  • Neither of the sample devices have the iPhone 4/4S form factor.
  • Neither of the devices are the final versions.
The iPhone 4S production last year didn’t catch momentum until late spring. If we judge the iPhone release pattern of last year, that is, the summer/WWDC pattern, we can say it’s just five months wait to see the iPhone 5 come out in the market.

tutorial : How to Install Siri on iPhone 4 without Proxy

Okay, this time it’s no proxy, no routing through various channels or any of that complicated stuff. We’re talking about how to install Siri on iPhone 4 and iPod Touch 4G without proxy – with as simple as a jailbreak and a simple change in the Cydia repo. Here’s how to do that:
Install-Siri-on-iPhone-4-3GS
How to Install Siri on iPhone 4 and iPod Touch 4G Without Proxy:
Step 1: Jailbreak your iPhone 4. You can use Redsn0w to do that and we have already posted about it.
Step 2: Cydia would have been installed now. Launch it. You will have to add a repo source to the Source on the app.
Add repo.siriport.ru to the Source.
Step 3: Hit the App store on Cydia and Install Siriport app. Once you’ve installed it, reboot the iPhone 4.
Step 4: Now this is where it gets a bit lengthy. In order to get Siri working, you need an iPhone 4S certificate. You can get that by pointing your browser to siriport.ru/1.crt.
Now, email the certificate file to yourself – open your email and get the certificate. Once you’ve done that, reboot.
or
Open siriport.ru/1.crt link on safari, it will bring up a certificate installation window. Tap on install button.
Step 5: Now, just activate Siri. It might get a bit on your nerves here so be patient. Say, ‘Hi Siri’ and wait for a while. About 1-4 minutes.
Now, if Siri hasn’t yet responded, say it again. Wait. If it still doesn’t budge, you will have to reboot the iPhone 4. Try again.
For the moment, as we haven’t yet had the chance to test it, this is all we could get to you. With disclaimers in place, we’d like to tell you that the device on the video seems to have activated Siri perfectly fine. However, we can’t be held responsible for any damage that might occur on your iPhone 4S due to the steps above.
Siri had long been ported to other devices but the problem had been in the certification. In fact, even this iPhone 4S certification is still under questions because it can soon be figured out by Apple. Although Siri ports have been known to work well on iPhone 4, iPod Touch 4G and even iPhone 3GS in a remote case, it looks like only now a publicly accessible and easily configurable Siri port has come to the fore.
Below is a video on how to install Siri on iPhone 4/iPod Touch 4G:

iPhone 4 Tutorial: Dealing With No Service

Here are some ways to troubleshoot when your iPhone 4 is getting no service.



iPhone No Service

 

 

 

The iPhone 4 is known for a number of different things, but taking great phone calls is not one of them. The iPhone 4 has come under fire since its first release because of iPhone antenna issues and dropped calls across the board. It is not uncommon to find the iPhone 4 with No Service listed where your "bars" should be, but the No Service phenomenon is one that is pretty common no matter what type of smartphone you are using. Here are a few tips for trying to fix the problem when your iPhone has No Service.

iPhone 4 Antenna

The reality is that there is a problem with the iPhone 4's antenna and you are not going to fix it easily. Instead you should try to troubleshoot these iPhone 4 antenna problems with the suggested methods. The easiest is to just use the duct tape on the side of the phone, or adjust how you hold the iPhone 4 so that you do not have a tight grip on the lower left hand corner. You should also use the free Bumper case that was offered to iPhone 4 users through an Apple scheme.

Troubleshooting

 

 

 

If you are not getting any service there are a few easy things you can start off trying. First, double check to see if your iPhone 4's Airplane

Mode is on, and if it is you will get No Service on your iPhone 4 even though it may not say No Service explicitly. You may have to wait several seconds, up to fifteen, after turning off Airplane Mode to find that you will have iPhone 4 service again. If that does not fix it try using the Sleep and Wake button once or twice to see if that repairs the service issue.
If you are seeing No Service independent of what you do on your iPhone 4 then you may be out of your general service area. This is less usual than it was in the earlier days of cell phones, but you still can get into regions where you lose service altogether. If this is consistent then you should contact AT&T to see your preferred areas and your data plan, but there is not much that you can do in the meantime to repair the No Service reading on your iPhone 4.




No Service and the 3G Network

 

 

 

 There are often times when the No Service message on your iPhone can be caused by issues with the 3G network. There is an easy way to troubleshoot this and it is even recommended by AT&T. Start out by going into Settings and selecting General. From here go to the Reset option and then choose Reset Network Settings. This will prompt you for a password if you have already put one in place. Once you have reset the network settings then your iPhone will take a few minutes to restart. Once it has come back hopefully your phone and 3G network service will return. This is actually a similar process to what you would do for an unlocked iPhone.

 

 

How to Jailbreak Your iOS 5 Device

The iPhone Dev-Team has done it again: iOS 5 has been out for only a week or so, but the group has already come up with a tethered jailbreak for devices running Apple's latest software. Here's how to jailbreak your iOS 5 device using the iPhone Dev-Team's Redsn0w tool.
Jailbreaking an iPhone allows users to gain root access to the device, as well as to install unauthorized applications. You might not know that Apple has a stringent App Store policy, and that it routinely rejects apps for a number of reasons, including smuttiness and other "content issues." Jailbreaking your iPhone will let you download unauthorized content from Cydia, which is the jailbroken equivalent of the App Store (don't worry--you'll still be able to use the real App Store).
For the first time, users do not need to manually supply their device's IPSW file. What this means for you is that the new Redsn0w jailbreak is extremely quick and easy to perform on any iOS 5 device (minus the iPad 2 and the iPhone 4S). The Dev-Team is working on an untethered jailbreak, but for now the tethered version is all that's available.

Can I Jailbreak My iOS Device?

Currently this jailbreak works only with the following devices (all must be running iOS 5):
  • iPod Touch 3G
  • iPod Touch 4G
  • iPad (original)
  • iPhone 3GS
  • iPhone 4 (AT&T/Verizon)
At the moment no jailbreak is available for the iPad 2 running iOS 5, or the new iPhone 4S.

The Risks of Jailbreaking

This jailbreak is currently incompatible with phones that have unlockable basebands. Do not try this if your phone has an unlockable baseband (and you want to keep it that way). Your baseband is unlockable/unlocked if you can use it on any (GSM, or SIM-card-using) network. You do not want to use this method if you either purchased an unlocked iPhone from Apple or unlocked your iPhone using a tool such as Ultrasn0w.
This is a tethered jailbreak, which means that each time you reboot your iOS device, you'll need to have it connected to a computer running Redsn0w, the jailbreak program. Basically, you won't be able to reboot the device if you're not close to your computer, so keep that in mind.
Before you do anything (even update to iOS 5), be sure to back up your device. How you back up depends on what type of data you have on your phone; I had a lot of photos, for instance, so I used Image Capture on my Mac to save all of my pictures to my computer.
When you jailbreak your iOS device, you risk turning your new toy into a paperweight--and if you accidentally brick your iDevice, Apple probably won't help you out. I've never had any problems with jailbreaking, but that doesn't mean you won't, so proceed cautiously.

How to Jailbreak an iOS Device Running iOS 5

Step 1: Install iOS 5
To perform this jailbreak, your device must be running iOS 5. To get iOS 5, plug your device into your computer and open iTunes. Find the device and select Update. Your music, apps, and data may be erased from your device, but you can update to iOS 5 without losing your data if you prepare properly.
How to Jailbreak Your iOS 5 Device
Step 2: Download Redsn0w
To jailbreak your iOS 5 device, you'll be using the Redsn0w jailbreak tool from the iPhone Dev-Team. Download either Redsn0w 0.9.9b6 for Windows or Redsn0w 0.9.9b6 for Mac.
How to Jailbreak Your iOS 5 Device
Step 3: Open Redsn0w, and Jailbreak
Double-cliick on Redsn0w to open it. A window will show two options: Jailbreak and Extras. Choose Jailbreak.
How to Jailbreak Your iOS 5 Device
Make sure your device is plugged in, and turn it off (if it isn't plugged in, plug it in first and then turn it off).
Then, click the Next button. Be ready, as you'll be prompted to hold down a series of buttons quickly in order to enter Device Firmware Update (DFU) mode. Redsn0w will walk you through this, but just so you're prepared, the series is as follows:
1. Hold down the Power (upper-right) button for approximately 5 seconds.
2. Keep holding the Power button and hold down the Home button at the same time for 10 seconds.
3. Release the Power button but keep holding the Home button for about 10 seconds.
How to Jailbreak Your iOS 5 Device
Once you enter DFU mode, Redsn0w will do the rest. Redsn0w will go through a series of screens--don't do anything, just wait.
Step 4: Install Cydia
Once your phone is jailbroken (don't unplug it yet!) Redsn0w will ask you to 'select your options'.
Make sure Install Cydia is checked, and click Next. (As mentioned earlier, Cydia is the jailbroken equivalent of the App Store.)
You'll see some stuff flash across your iOS device's screen, and then your device will reboot (tethered) in a jailbroken state.
How to Jailbreak Your iOS 5 Device
Step 5: How to Perform a Tethered Reboot
Now that your iOS device is jailbroken, you can reboot it only while it's tethered to your computer. (If you reboot untethered, Cydia and Safari may crash.)
