Iphone’s that usually come with a contract locked to access services through a particular career like AT&T will now be available contract less. With Sim Free iPhone 4 that is already unlocked can be used with any GSM provider worldwide no matter which country you purchased it in. Before this you have to Jailbreak your Iphone to make it work on other networks .
