Switching iPhone 4 from AT&T to Verison?

I have an iPhone 4 from AT&T and replaced with new iPhone 5. I have a friend that is with Verison, wondering if I can give her my old iPhone and can she use it with her plan?

NO you can use a AT&T phone with verizon they are not compatible as one company is GSM and the other is CDMA

Not possible.

  • Would switching my iPhone 5 for a iPhone 4S be stupid? I think the iPhone is great but I like iPhone 4S design better and aren't they pretty much the same just with a few more features? Would it be a dumb move?
  • Will my verison iPhone 4 work in China? I'm going to China for 10 days in November and I'm worried that my phone won't have service being I'm from The USA. I have Verison and its an iPhone 4. Will it possibly have Internet but not be able to text or make calls. I've heard that it will text but no calls and I've heard that nothing will work, not even Internet. So I'm just trying to get a real answer. Does anyone know from experience or work for verison or something?
  • Will my AT&T Sim Card Work on My Verison iPhone 4S? My version iPhone has a sims card slot on the side, so do i need some tool to unlock it for me? Ok so how do I unlock it?
