I am currently on tmobile using a vibrant. The bugs with the vibrant are starting to bug me, and there is no where else to go to for tmobile. I am thinking about going to sprint for the EVO. I will have to figure out a way to get out of my tmobile contract, (hasn't been 14 days) if anyone wants to help me with ideas. my main question is, is it true that you have to pay an extra $10 a month for the Evo? I don't have 4G in my area, do I still have to pay for it? What kind of deals can I get from sprint for a new contract? Can I keep my same number?
