Unlocked AT&T iPhone 4 Working on Sprint Network?

My friend is planning to give me his iPhone 4 when his cousin gives him his hold iPhone 4S but i'm wondering if his iPhone 4 from AT&T Thats unlocked, will it work with my sprint network?

No, AT&T is a gsm network and Sprint is a cdma network. They are incompatible technologies and therefore it is impossible.
You could put it on the AT&T smart phone Gophone plan for $65 a month for unlimited talk, text and lots of data. Call them about it.

No it will not work.

Sorry to say but as others answer that it, s not working.
