Switching from MetroPCs to Sprint

[emartinez13]

Hello all, I have an Alltel branded Touch Pro and for the past few days i've been thinking about getting "real" phone service and switching from metropcs over to Sprint. I've spoke to 2 different reps and they ran my esn and they said I could put my alltel tp on their service with no problem. I guess my questions here are...

1. Do I have to relock my phone and should I flash a stock Sprint rom on to it or put an original alltel rom on it since its an alltell phone?

2. Should I not mess with anything and just bring it to a sprint store so they can do whatever they need to do to it?

My main concern with whatever I do is that since i'm on metro i have crappy 1x speed internet and have never had evdo, is setting up the evdo on the phone something I can do (epst settings?) or something they have to do?

Thank you all for any input.
