Hi there, I'm currently on Simplicity with O2 - been trying to upgrade at an O2 shop in London for the last two days, but no dice due to the stock situation. As the Apple Store on Regent's street have stock to burn, is there anything to stop me buying there as a new customer? I know i'd lose my number, but that's not a huge issue - can anyone think of any other drawbacks? Sorry if this has been posted before - I looked but didn't see anything. Thanks for your help.
