Using unlocked iPhone 4S with carriers in USA
I have an unlocked iPhone 4S from UK, which i have been able to use in verious countries on GSM network, so now i'm shifting to States and i want to use my iPhone 4S on Sprint or Verizon.
1) Can i use CDMA network?
2) will i still be able to use GSM?
3) will my iphone still remain unlocked or will it be locked?
iPhone 4S, iOS 5.1.1
