A:Answer If the Motorola Rep that answered this question is actually correct no one with T-Mobile service should consider this phone. Lack of B71 is one thing, but no B12 makes this phone useless on TMO other than in the heart of cities. Move even in to the suburbs and TMO coverage will be very poor. How does Motorola think releasing a GSM Only phone in the US, without B12, make any sense? This shouldn't be a Best Buy exclusive, it should be an AT&T exclusive as that network is the only one it will have decent coverage with. Insanity.
