We believe carriers such as Sprint, Verizon and AT&T should offer iPhone Unlocking for Users to give to family or use the iPhone on another service such as T-Mobile USA or International carriers such as Vodafone, Mobinil, and Rogers. T-Mobile USA does not offer the iPhone but does offer Support for it, and offers Micro-SIM Cards for use on iPhone 4 and 4S and Regular SIM Cards for use on iPhone 3GS/3G and the First Generation. Sprint and Verizon are CDMA Carriers, but the iPhone 4S was made to be a World Phone, and it supports both the GSM (T-Mobile/AT&T/Worldwide) and CDMA (Sprint/Verizon) , So we think the iPhone Carriers should offer Official Unlocking for any Domestic and International use !
