If the only reason you are switching from Verizon to T-Mobile is due to the newer tech phones, I'd suggest looking at the Droid Bionic for Verizon. I'm waiting for one to hit for my next upgrade.

Dual core (2 GHz total processing power), front camera, 8 megapixel camera, 4G/LTE capable (area is growing steady but slowly). Comes out in a month or two, depending on what rumor you want to believe. Also the fact that AT&T will most likely purchase T-Mobile, I'd stay away from a new contract with them. If there are other hidden reasons you want to switch away from Verizon then ignore this
