AT&T started its pre-orders for the Samsung Galaxy S III earlier this week, with the 16GB model priced at $199.99 on a two-year contract. The company now says that orders are scheduled to begin shipping on June 18th, just ahead of Sprint's release on June 21st, but there's still no mention of a 32GB model — unlike Verizon, Sprint, and US Cellular who are offering 16GB and 32GB versions.

AT&T's Samsung Galaxy S III will run on the company's LTE and HSPA+ networks. The four major US carriers all have the S III available on pre-order but AT&T is also stocking an exclusive red version. We were impressed with Samsung's latest Android 4.0 handset in our review, describing it as a technological triumph with one of the best cameras for an Android device.
