The next Sidekick was approved by the FCC yesterday. Although a number of documents and pictures are still confidential, there are clear pictures of the front and back in the filing with T-Mobile branding present. The new body has a smooth face that uses resistive buttons hidden below the surface of the phone and trades out the scroll wheel for what appears to be the scroll nub from Apple's Mighty Mouse. The back shows a 1.3 Megapixel camera with flash, memory card slot and removable battery. In addition to these physical improvements the Sidekick 3 will have tri-band GSM (850/1800/1900) as well as Bluetooth.
