I'm going to New York in December for a holiday, and I noticed that due to the exchange rate I may be able to afford an iPhone 3GS or iPhone 4. What I was wondering however. Is there anyway that I can buy just the phone, without having to choose a plan? What I basically want to do is this. Buy the phone, return to the UK, have the phone unlocked and insert my Orange "Pay As You Go" Sim Card and use it from there. Is it possible? I've heard many different things, some saying it will, some saying it won't.
