T-Mobile UK told The Register that they are talking with Apple about securing the iPhone 3G on their network in as little as a few months. O2 still seems to be secure as the exclusive iPhone 3GS supplier for the British Isle.

Like AT&T’s relationship with Apple, O2 has had exclusive rights to the iPhone since 2007. Rumors in the US indicate that the device will not be available for other carriers until 2011, when the 4G network is emerges.

If the iPhone were to be available on another carrier, which would you choose?
