This is the protocol used to talk to the old, and probably the new baseband, at the bootrom level. The old bootrom didn't have a sig checking, the new one does. (correct me if I'm wrong, but I do not manage to dial with the naseband on my iPhone 4, using minicom, he doesn't answer to the at commands...)
Protocol
AT 0x30 2 byte length n byte data 2 byte checksum sends A5 on success, 5A on failure
3G
Correct me if I am wrong, but on the iPhone 3G bootrom, the "protocol" section is pretty much identical, besides the last line, which is instead this:
sends 01 on success, FF on failure
