hi guys im back, lol......my second post...i really thought this thread would be dead by now but obviously not 
anyways.....like i said before....the guy in the previous post said he was using a 1.1.1 US iphone...which had different bootloader. All i said was that it wont work on an OTB 1.1.2 US iphone.
secondly....someone said it might not work with my o2 sim as its already activated. well....few weeks before i got a UK iphone for my sis...jailbroke it and activated it using a generic o2 pay&go sim. what did i do with the original iphone o2 sim??....well i kept it...and first thing i did when i got US iphone was to put it in that and see if it would fool it into thinking it was an o2 iphone....guess what.....didnt work guys.
The reason we cant do a true unlock of 1.1.2 otb iphones is because the bootloader is different...so im sure that when its locked to AT&T in the states or o2 in the UK it has something to do with the baseband...not the firmware.
hope this clears few more things up guys.
