I've switched to t-mobile about 3-4 months ago and i had bought the dash 3g. However, a new phone (htc touch pro 2) just came on the market for $350 with the contract. I want to switch to that phone. If I went to my neighborhood t-mobile store, would they let me buy the phone for $350 or would I have to pay extra since i'm already a customer for 3-4 months? Thank you so much for the help. =]
