Join Date: Feb 2006 Can an iPhone bought in the US be activated in the UK or Germany? 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.

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