T-Mobile has refreshed the Sidekick 3 by bringing out two special editions. Features remain the same as the original Sidekick 3. There is one model designed by both Lifted Research Group (green) and Diane von Furstenberg (black). Features of the Sidekick 3 include IM (AIM/Yahoo/MSN), MP3 player with suport for stereo headset, miniSD card slot, Bluetooth 2.0, 1.3MP camera, and EDGE high-speed data support. The new Sidekick models will go on sale in store and online starting on October 30th. With a 2-year contract the devices will sell for US$345. That’s a slight premium over the original Sidekick 3 which is currently selling for US$299 online.
