Jailbreak news has been a hot topic recently, as iOS hackers are updating their progresses on untethering.

Pod2g from the Chronic Dev-team and MuscleNerd from the iPhone Dev-team are working hard to provide an untethered jailbreak for iOS5, particularly with A5-powered iDevices. There are already two jailbreak solutions out there for iOS 5, but both of them are tethered and they do not work with iPhone 4S and iPad 2, which are A5 devices.

In his blog, Pod2g states that he had completed the iOS 5.0.1 untethering codes for iPad 1, iPhone 3GS and iPod 4G. As per reports testing has gone well and the jailbreak is covering every variation of A4 devices, which will please a lot of users. Though earlier Pod2g of the Chronic Dev-team posted a video link demonstrating an untethered jailbreak, there is no confirmation that the same coding will work with A5 devices such as the iPad 2 and iPhone 4S, but we are sure that these will follow in time.

While Pod2G gave no updates regarding the jailbreak status of iPhone 4S and iPad 2 in his previous update, he has now disclosed that the research work on the jailbreak solution for the iPhone 4S and iPad 2 has also been initiated. MuscleNerd from the iPhone Dev-team also tweeted that the upcoming redsn0w release will ensure that both TinyUmbrella and Cydia blob saves are useful for 5.0+.

The hackers like Pod2g and MuscleNerd are hard at work trying to access areas of our devices that would otherwise be untouched. But as the iPad 2 and iPhone 4S run on Apple’s latest processor A5, it is difficult for hackers to find a jailbreak for the iPad 2 and iPhone 4S as they were unable to find a bootrom-level exploit in the A5 processor.

The bootrom-level exploit is a low level exploit which can only be patched by revising the hardware. No update in the operating system can patch the low level exploits. Finding exploits in the bootrom level is a big achievement since Apple won't be able to fix it without a hardware revision. While the new bootrom revisions have an exploit, this will need the support of a firmware-based exploit for achieving an untethered jailbreak.
