This is an S5L8720 bootrom revision for iPod touch 2G devices sold between September 2008 and September 2009. It is located at 0x0 and uses SDRAM @ 0x22000000 for global variables. It patches the Pwnage exploit, as the bootrom now properly checks LLB's signature. This bootrom is, however, vulnerable to the 0x24000 Segment Overflow and the usb_control_msg(0xA1, 1) Exploit.
