Can a US iphone (1.1.2 OTB) used on with O2 sim (contract one) without unlocking?
I got an iphone (1.1.2 OTB) from the US and I would like to know if I would be able to use it with my O2 sim when I get back to the UK (with just jailbreak and activation since unlocking is not yet possible). I do have a contract with O2 for the last couple of years.
I know for sure this works for UK iphones as a friend of mine tested this successfully. Before getting various replies let me explain my friend's case. He got a new iphone from the UK (1.1.2 OTB) and he has the exact same contract with O2 like I do. He jailbroke it, activated it and then used his O2 sim. He is now able to make/receive calls/sms etc.
So basically do UK iphones are different from the US ones?
