Alloc8: iPhone new Bootrom released

The release of Alloc8 Bootrom has bought more freedom to the iPhone 3GS users than ever before.  This feature has handed the users complete control over the device. It was released quite late as by the time it was released, iPhone 3GS has become history and very few were actively using it. It has not been released publically except Limera1a, which only give supports up to iPhone 4. The late release shows that Apple`s legendary iPhone3GS hardware is capable of jailbreak in an untethered way.

The original version of iPhone 3GS had a vulnerability in its Bootrom. This vulnerability was browbeaten by 24Kpwn because of its low level nature. Alloc8 is released by developer axi0mx via GitHub project and all necessary information and links are mentioned on GitHub website. The developer says, “It’s not a typical heap bug, bug in implementation of heap itself”.

Alloc8 will now give complete power to user for upgrading, downgrading, untethered jail breaking and installing of custom firmware. The great part of this new release is that no software or firmware update is needed to patch it with the Bootrom, only an update is required. This seems incredibly valuable for developers and Apple itself. Initially 24Kpwn was worry for Apple as they released a refresh of iPhone3GS in the mid of their release cycle with new Bootrom.

Alloc8 works on both old and new Bootrom. It exploits the powerful vulnerability in Malloc function implemented in Bootrom. Alloc8 is implemented in IPWNEDFU jail break tool. This tool works on command line only. Apple has rare hardware level exploits and most of the exploits are based on the userland exploits. Apple will face difficulty in patching Alloc8 IPWNEDUF, because they are hardware level patches. They can only be implemented if Apple changes the hardware.

Still this announcement cheers up all the Apple lovers and especially those who are still using iPhone3GS. This late update may not be of worth in this modern smart phone world but still can’t be ignored as it is made on Bootrom (Hardware) level.
