Hey, so I think I want to reserve an iphone 4 from my local Apple Store, but I'm currently still 1 month in my T-Mobile contract (eligible for upgrade). Are Apple able to do upgrades in store for me, or can they only open new contracts? I don't really want to have to change my number! I noticed on the US Apple store, there was an option for AT&T customers to do it, but I wonder if the same is true in the UK. Anyone got any previous experience from past iPhone launches?
