Okay. So my sister's boyfriend gave me his old iPhone 3GS. It is AT&T. I have Sprint. I've read all over the internet that you can't switch carriers between AT&T and Sprint and that you can switch carriers between AT&T and Sprint.

I want to know these things:
1) Can I make the switch
and if I can
2) How do I do it & how would I go about the SIM card deal

I don't like the iPhone 4 design so I'm really hoping that I can get this one to work. Please help! Thank you!

Don't think it can be done they are different system types and the gs was built only for AT&T.
