Documents became public today on the FCC web site that detail an unannounced Nokia phone for AT&T. The Nokia 6750 “Mural” is a clamshell phone with dedicated music keys and an outer display hidden behind a mirrored shell. Documents confirm 3G in the 850/1900 bands that AT&T uses. Also confirmed are a memory card slot, Bluetooth, and a camera. The early draft user manual refers to Video Share and Media Net - both AT&T service brands - and the keypad has a dedicated “CV” button for AT&T’s Cellular Video service. It is not clear if the 6750 will have the S60 smartphone OS like the 6650 fold.
