Filings with the FCC confirm that Samsung's upcoming A877 handset will support dual-band GSM, EDGE and WCDMA networks, while offering Bluetooth connectivity. The handset is said to feature a 3.2-inch AMOLED touchscreen and a slide-out QWERTY keyboard with a fourth row of keys. An internal accelerometer will allow the screen orientation to automatically switch from portrait to landscape mode when the phone is turned.

Samsung has yet to announce additional details, but an unconfirmed rumor claims the A877 will launch with AT&T near the end of the month. [via Phone Scoop]
