Unless I misunderstood, there is no way I could get facetime to work on a non-authorized carrier in the US? I bought a factory unlocked iPhone from the UK and now using it on t-mobile. So far I haven't been able to activate Facetime and waiting for 4.1 update with the promised email-based activation. Now I'm on 4.1 and at loss as to how exactly I can get this thing to work. any idea?
