Why not ?
Is the iPhone locked to an AT&T SIM card ?
If the iPhone is tri or quad band then surely it will be able to pick up a carrier in the UK with another SIM inserted....
Yes, the phone will be locked to an AT&T sim
for how long in wonder ?if anything like Apple TV's OS it will not take long for some bright spark to tweak the OS
I remeber hearing in one of our AT&T meetings that it's a MULTI Year Exclusive contract I think it was like 5 years or so.
I would be buying the phone from AT&T but when traveling in Europe I would prefer to buy a pre-paid SIM card from a local service provider and most of all I'm interested to know if the web and map functions will work roaming in Europe.
