Sprint HTC Hero to Alltel?

[XombieJer]

Would it be able to flash a sprint android phone to alltel? I can get one for 250 on ebay or I gotta wait 3 months and I am very eager to get this phone =p.

Is it pretty complicated too? I've searched around the forums for a bit before posting this and it doesn't seem too complicated but I just wanted to double check since this is an android phone and this phone just recently came out for alltel.

Edit: Just found this...

Thanks,
