Some lucky customers have a chance of getting their AT&T Samsung Galaxy S III sooner than the 21st of June. Right under the pre-order button in the screenshot above is a side note stating “Arrives on or before 6/21/2012. Other carrier dates are not confirmed except that of T-mobile’s network which is planned to arrive on the 21st of June as well. This isn’t a lot of news but it sure makes it feel like anyone could start receiving these devices early. In the mean while I guess you’ll just have to wait until your package comes.
