Well, what do you know - another Galaxy S III leak! Only this time, it's directly from the source. You see, the Galaxy S III has made an appearing in Samsung's own program used to manage its mobile devices, called Kies.
This basically verifies two bits of information: the device name and model number. There have been rumors that Samsung may call it something different and make it more of an incremental upgrade to the S II, but unless there's a change of heart between now and the release, it looks like it's officially going to be called the GSIII.
