S5L8720

This is the Application Processor used on the iPod Touch 2G.

Exploits

iBoot / Kernel Level

• ARM7 Go - Firmware v2.1.1

Bootrom

• 0x24000 Segment Overflow

Boot Chain

VROM->LLB->iBoot->Kernel->System Software

It is definitely worthy to note that the Pwnage exploit is fixed because the images are now flashed to the NOR in their encrypted IMG3 containers, and the bootrom can properly sigcheck LLB.
