Ultrasn0w (with preserved baseband) on 4.3..

NO NEW UNLOCKS HERE! FOR USERS WITH BB VERSIONS CURRENTLY SUPPORTED BY ultrasn0w ONLY! PLEASE RTFM!

4.3 seems to have enabled slidable image address randomization (ASLR). This broke ultrasn0w code naively using 0x1000 as the main executable base address. In addition to that, its FindReference function was using hardcoded offset/xref pairs for slidable images, which means every fw update will break it.
So, I've written a small dylib that works around those issues.

Only tested on 3GS; will require changes for next betas.

Hello to the famous msft guy!

I'm a complete jailbreak novice here, fresh off the forum, with a questions about a missing compiler flag. Hopefully this is an okay place to ask it?

I'm trying to do a tetheredboot on a 3GS running 4.3.5 and a MacBook running 10.5.8. A friendly fellow on Hackint0sh suggested that perhaps you missed a compiler flag which prevents the binary working on 10.5.x. He said:

"All you can do is try and bug msft.guy to compile this again with -no_compact_linkedit in the compile options."

Are you bug-able about this?
