Samsung Galaxy S III hits FCC today for its release in North America. This device supports AT&T’s HSPA+ radios, but will not work on T-Mobile’s as those users would likely be stuck on Edge. You will not find any LTE connectivity here. The regulatory label also does point towards the availability of a 2,100mAh battery that is said to last for up to 10 hours under full load with its machinations being taxed to the maximum. No North American carriers have announced plans to carry the device but we’re alright with assuming some will in due time.
