This morning, Nokia posted details about a forthcoming high-end clamshell with S60 and AT&T branding.
The Nokia 6650 is expected to replace the N75 clamshell and will feature an outer display with a user interface that is controlled by touch sensitive controls directly below for the most common functions.
The inner display will be a large 2.2 inch QVGA display like the N75, as well as a dedicated button for GPS services like AT&T Navigator, thanks to the inclusion of A-GPS support as well as a dedicated GPS transceiver.
The rest of the featureset is similar to the N75 with quadband GSM/EDGE, dualband W-CDMA access, the addition of Bluetooth with stereo audio support, 2.0 megapixel camera with flash and video recorder, microUSB port, microSDHC expansion slot, AT&T services such as Mobile Music, Instant Messaging, and Push to Talk, FM radio with RDS, and Series 60 Feature Pack 2.
There is currently no timeframe for release at this time.
