Devices that appear to be Samsung Galaxy S III models are being approved by various agencies. The Bluetooth SIG approved the SGH–I747 and SGH–T999V, both which appear to be the Samsung Galaxy S III. The t model is T-Mobile and the other should be AT&T according to previous naming schemes.
The FCC has approved model SGH–T999 that supports 1700MHz, 850MHz and 1900MHz, all T-Mobile bandwidth. FCC approval is usually a good sign with release dates following within a few months after approval in many cases. However in previous years, Samsung Galaxy releases were months after European releases.
Initial reviews for the Samsung Galaxy S III have been positive, some reviewers don't like the plastic case while others raved about the software.
