I stopped by a T-Mobile store today to look at the Sensation-4G. I really liked it. With a bigger battery and an efficient CPU, this may be the first HTC that does not have a battery problem. But the deal breaker is that T-Mobile does not have a Canada plan and I am traveling there a lot these days. The sales person suggested that I get a prepaid SIM card for use when I am there. I pointed out that it requires an unlocked phone. She initially claimed that the Sensation-4G would work with any SIM card right out of the box, but after I pushed her to check with a manager, she changed that to claiming that if I explain my situation to T-Mobile, they would unlock the phone as soon as I am past the 14 day trial period. That whole exchange sounds a bit fishy. What have people's experience been with T-Mobile's willingness to unlock their Android phones?
