Looking for a new, unlocked iPhone that hasn't been hacked? Normally iPhones come locked to a carrier, such as AT&T, and must be modified to allow usage with other networks. This could violate terms of service and Apple's warranty rules.
Two iPhone models that have never been locked can now be found for sale on the website Buy.com. These legally unlocked iPhones should be fully covered by Apple's warranty and make it possible to use the device on many GSM networks with no contract.
