can i buy an iphone in the US that I can put my sky mobile o2 sim card in?
Several years ago I bought 2 iPhones in the US when I went on holiday (I live in the UK.) I have a Sky Mobile contract at the moment and Sky use the O2 network. Can I still buy an iPhone in the states that will work in the UK with my current sim? If so what carrier do I need to choose when buying the phone? AT&T, T Mobile or something else? My parents are out there so don't want them to buy and bring back and it not work
