I currently have the Freeform with Alltel prepaid. I've recently become interested in maybe buying a blackberry or some other smartphone off of eBay, and activate it on my prepaid Alltel account.
Do you think this would be a good idea, and would it be worth it? I could pay $60 a month for unlimited talk, web, & text, all while still being considered prepaid, with no contract.

Should I do this?
