We know the Samsung Galaxy S III will hit the U.S. this summer, but we have no idea when or exactly what carriers. We’ve heard rumblings that it could land on all four major carriers. Meanwhile, at CTIA, they specifically told me that it would be on available in the U.S. as an HSPA+ device as well as the fastest LTE network. We have further confirmation for T-Mobile and AT&T as it appears those two variants made its way through Bluetooth certification.
Model SGH-I747 appears destined for AT&T and Amazon seems to agree. Model SGH-T999 appears to be headed to T-Mobile. We’ve already seen this model show up on the global Galaxy S III. We’ve also seen both of these models show up with test shots recently. Those test shots also indicated model numbers for Sprint and Verizon as well, which are SPH-L710 and SGH-I535 respectively.
Now the question is when? Samsung will most likely host an event in New York City in the early Summer to announce all the variants. At that time we will have a firm handle on when we will see them. I am guessing August, but am hoping for July.
