AT&T is finally set to launch its first 3D smartphone, the LG Thrill 4G. No, that 4G doesn’t mean users will be able to take advantage of AT&T’s soft launched 4G LTE network, but the Thrill will begin burning up AT&T’s previous-generation fourth-generation network when it becomes available for purchase this Sunday, September 4th. We reviewed the LG Thrill 4G last month and we were a little surprised by the fact that we really did enjoy recording and viewing 3D content on the device. Overall, however, we found the Thrill 4G to be a mediocre phone that’s bulky, heavy and not overly competitive with modern Android offerings from the likes of HTC and Samsung. At $99.99 however, those looking to play around with the 3D features shouldn’t be disappointed.
