On Friday AT&T made an announcement that surprised many of us who had given up waiting: customers with an out-of-contract iPhone can unlock it to work with any other GSM SIM — like from T-Mobile. Now the official unlock is here, and the process is actually pretty simple.
Before you attempt to unlock you need to make sure your account isn’t in a longterm contract, your iPhone isn’t on a contract, and that your account is in good standing with AT&T. After that, the process is pretty straightforward.
