Are you excited that a 3D phone is coming to AT&T? If you answered yes, sit down and think happy thoughts, because we're now hearing that the Thrill 4G -- aka the LG Optimus 3D -- may be delayed once more. According to a screenshot leaked from Radio Shack, the ill-fated device is getting pushed back to a tentative September 4th launch date for unknown reasons. As such, the reseller's putting a halt on pre-orders of the phone until further notice. We've reached out to AT&T for official comment and will let you know if we hear anything back. Regardless, at the rate this phone is going, the Thrill is quickly devolving into a depression.
