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

Exploits

iBoot

Note: iBoot on the S5L8720 can be downgraded, allowing any of these exploits to be used on future firmwares

Bootrom

Kernel

Userland

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 check LLB's signature. That being said, unsigned images can still be run using the 0x24000 Segment Overflow, provided the bootrom is old enough.
