I have heard this for a while now from all my friends who are on T-Mobile. My question is, if i get a Curve on T-Mobile now, will I be able to use the 3G network when it comes out, or will I have to 1) Get a new device, and/or 2) renegotiate my contract?
The Curve is not a 3G compatible device, only EDGE. So, you can either buy a new device outright (if you aren't eligible for upgrade), or try to renegotiate your contract for better pricing on the new device, LOL.
