We already had plenty of reason to believe that Samsung's QWERTY-packin', landscape-layin' SGH-a877 was headed to AT&T, but now it's pretty much a lock. phonescoop has dug up a few more pertinent details about the so-called Impression, confirming the 3.2-inch AMOLED touchscreen and adding that the handset will include an accelerometer and built-in Bluetooth. If this one has your eye, we'd wager that it won't be long before it goes on sale for real -- maybe all's that is left is a formal CTIA unveiling?
