Buying Sprint Pro to switch to Alltel...Good idea? Bad idea?

[thejoshster]

OK, so I'm aware of most of things involved in switching this phone from sprint to alltel. But if anyone who has done or attempted to do it could say if its worth it or not. I am worried about unsolved issues like roaming icon on the diamonds, data settings, modem rom, ect...Maybe wait till a leaked rom comes along? idk, i am looking at getting one on ebay and switching it over. Anyone with expierence or advice, feel free to share!
