How to unlock a Sprint iPhone with the factory unlock code?
So i'll be calling Sprint in a couple days to get the factory unlock code for my iPhone 4S once i'm donw with my contract, so what do i do next with that code to factory unlock the phone? And eventhough it's unlocked could it still only be used with Sprint or Verizon (since it's a CDMA phone) or can it now be used with networks like AT&T or tMobile?
