Sony Ericsson just announced their new M600 handset. This 15-milimeter-slim, 3G flip-less sibling of the P990 is a dual-mode communicator bringing UMTS and tri-band GSM/GPRS with a touch-sensitve, 2.6-inch 240x320 262K color display, dual-function QWERTY keyboard, RSS reader, and Bluetooth with A2DP stereo audio support for untethered playback of that MP3/AAC audio stored on the 80MB of internal memory or Memory Stick Micro expansion card. And like the P990, the M600 is the second SE phone to feature the Symbian 9.1 OS and UIQ 3.0 interface with support for a wide range of push email for business users including BlackBerry Connect, Seven, Vista, and more. Available Q2 for Europe and US in Black or White for a yet to be determined price.
