I'm planning on getting the new iPhone when it comes out. I have an iPhone 3G that probably isn't worth very much money (some scratches).
If I give it to a friend who is already on AT&T, can they just pop in their SIM card and get a data plan from AT&T?
If I unlock the phone, can they use it with other carriers (do their data plans work with iPhones?).
TIA
