Many people have been wondering about the jailbreak release date for iPad 2. Unfortunately, the jailbreak is taking longer than usual because Apple has greatly upped its hardware/software, making it harder to bypass.
To understand a little bit more, here is a little explanation in layman’s terms:
Jailbreaking an iDevice means gaining access of the root read/write permissions, which means you can choose what apps you want to run on your device (not just the apps available on the App Store). In order to untether an iDevice, some modified code must be inserted into what is known as the bootrom. The bootrom is a snippet of code that runs at startup time, and checks on the status of the boot image. It’s generally used to verify that the image has not been corrupted, but can also be used to check for unauthorized firmware. The 24kpwn exploit – otherwise known as 0x24000 Segment Overflow – bypassed the signature checks on iBoot and allowed unsigned firmware to be loaded.
So you might be thinking now, well ok, find the bootrom, and insert the modified code in it and there you go. Well, that may be the case, however, hackers have recently discovered that in the new A5 chips (the iPad2’s processor), the bootrom simply isn’t there! This gives rise to a popular theory that once the A5 bootrom is off, it stays off until power cycle. So this means that the bootrom is actually inside the A5.
So, bottom line, is that to gain access to the bootrom, some reverse engineering is required, and that is what is taking time. However, there is a silver lining here: Since all new iDevices will have the A5 chip in them, once the iPad2 is successfully jailbroken, so will all the others. This means that a possible untethered jailbreak for iPhone 5 might be available before the actual iPhone 5 is released!
Stay tuned to learn more about the ETA of the jailbreak. At least you now understand what is the hold up.
Important Note : If you own iPad 2 running iOS 4.3, you have to keep it and don’t upgrade to later versions (4.3.1, 4.3.2), as the upcoming iPad 2 jailbreak may land at the beginning on iOS 4.3. Please let your friends know this important advice.
