Alloc8 Exploit

The alloc8 exploit is a bootrom exploit used to run unsigned code on the both the new bootrom and the old bootrom iPhone 3GS (and thereby jailbreak it). It is the first public untethered bootrom exploit for the new bootrom iPhone 3GS.

axi0mX, the discoverer of the exploit, produced a detailed analysis of alloc8, which was published on GitHub.

ipwndfu is currently the primary and most simple way of using the alloc8 exploit.
