Today Samsung published some information on the SGH-a877 Impression. This sideways slider has a 3.2-inch AMOLED touchscreen and a full, physical QWERTY keyboard with four rows. Samsung confirms that the a877 has an accelerometer and will auto-rotate when turned on its side. FCC documents confirm that the a877 will have at least dual-band GSM/EDGE/WCDMA and Bluetooth radios on board. No other information was available, but the a877 model name and carrier branding suggest that it will be offered by AT&T.
