I was just wondering if a US Iphone is locked to A&T carrier. Is it possible to use a O2 pay and go sim on it?

yes i was goin to ask the same question...can anyone help on this question by YOUGOTMAIL!

or even o2 contract sim???

I think you'll find that a US phone will be locked to A&T sim cards only. O2 cards won't work.

u got this from a reliable source? 100% sure?

dude it's not called locked for fun

it's call locked cuz it's locked to the carrier it come from

there is NO CHANCE AT ALL that and O2 card work in an locked At&T phone

and b4 you ask if its a 1.1.2, no there is no way you can unlock it whitout turboSim or something similar

Hope This Help

ye cool...i think im goin to b buyin a turbosim or somthing as i dont knw wen firmware 1.1.3 comin out...cus if that comes out without bootloader 4.6 it can be unlokd...but for now the turbosim situaton....im gna giv it a couple more weeks.

Aww, I am very dissappointed. Am able to get an Iphone(US) for about $400/£200. Might as well use it as an Ipod touch, as I am not sure how future proof these sim solutions are.

the turbosim, stealthsim is 100% guaranteed....otherwise gotta wait and c if 1.1.3 is bootloader 4.6 or not if so...messy shit...we gota buy the turbo simss...ye lol gotta use it as ipod touch wit camera...haha im stuk wit this situation too
