Hi, I currently have a jailbroken phone which I bought in the US. I moved to the UK and my phone is still under warranty (well I jailbroke it so that voids it right) and there is a chip in the phone right by the headphones. Usually when there is a crack they'll replace the phone. If I get the american iphone replaced in the UK will they give me an unlocked phone? Also will they replace it since it is jailbroken?
