Apple’s fifth-generation iPhone 4S can now be SIM-unlocked in just a few easy steps, as can any previous version of Apple’s popular smartphone line. The new unlock procedure, mapped out this past weekend by mobile hacker “Loktar_Sun,” will allow iPhone owners to use a SIM card from any compatible carrier rather than just the carrier from which the phone was purchased. Users need only jailbreak their iPhones and follow a simple 13-step procedure to unlock their handsets, though caution should obviously be taken and the procedure will void the manufacturer’s warranty. This is a great option for international travelers and those who want to use an iPhone on T-Mobile’s U.S. network, however, and numerous users have successfully used the guide to unlock their iPhones.
