I have my evo on one line but the main number I have given out to everyone and use daily is a different line/phone. I am liking my root evo so much I want it to be on my main line. What is the best way to do this? I have seen stuff to manage phone online at sprint site, I guess i could just call them on the phone and see if they can do it. Don't wan't to take it in and have it done since it is rooted. Suggestions, experiences?
