I have had quite a few problems with the proximity sensor on my HTC ThunderBolt 4G (I'm actually on my 4th Like-New Replacement phone) and the problems are starting to appear again which are quite obnoxious. If I call Verizon, would they consider sending me a different model of phone? I'm an HTC kind of guy so I'd probably wait until the Vigor is released to ask for a different phone. Anyone know if this is possible?
