AT&T is set to launch the LG Trax, a clamshell phone that merges both the carrier’s faster mobile Internet linkup with a dedicated music phone. The Trax includes touch-sensitive external music controls; it also has a quick-access button inside that jumps to the media player no matter where the user may be in the phone’s menus. LG additionally brings extended microSD card support up to 4GB and playback of AAC and WMA tracks beyond the more typical MP3 format. As the device runs on AT&T’s HSDPA network, it also taps the provider’s Internet music and video streaming services. Runs with a  1.3-megapixel unit doubles both as a still camera with pre-shot adjustments as well as a video camera for AT&T’s Video Share one-way live streams to other 3G phones. No official announcement of the phone has been made but should take place during the summer and at a low price compared to most of AT&T’s 3G-equipped hardware.
