Because of the date the 0x24000 Segment Overflow was leaked by NitroKey, Apple may or may not have had the time to fix the bug in the iPhone 3G[s] Bootrom. If not, the following needs to be done:
- Find a new iBoot exploit - This will allow us to decrypt the platform iBoot and other firmware files in it's IPSW, as well as dump the bootrom to examine.
- Find a new bootrom exploit - After we have the bootrom dumped, we must look for a way to make SecureROM run our patched LLB.
