Bootrom 240.4

iBoot version 240.4 is an S5L8720 bootrom revision for iPod touch 2G devices sold between September 2008 and September 2009 (MC). 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.
