Can an iPhone bought in the US be activated in the UK or Germany?

[67952]

I'm thinking of buying an iPhone when I got to the States to visit my mom. If I buy one there, can I bring it back to London and activate it with O2 here?

I'm NOT talking about unlocking the sim. I'm asking if an iPhone bought anywhere in the world can be activated with any of Apple's cellular providers in their respective countries.

Good question. But as long as the Euro iPhones are not out no one knows if they have the same firmware (same baseband?).

Of course it won't, yor IMEI number on the phone is locked to the carrier, the agreement between apple and the carrier is that the phone always stayed locked to the carrier.
