T-Mobile's next-gen Sidekick is now being claimed as real and has received additional details. Now referred to as just the Sidekick 2009, the messaging phone is described by an anonymous source for Hiptop3 as having a "more grown up," upscale feel and should have a new version 5.0 of Danger's Sidekick operating system. A set of lights along the top edge of the display contribute to the phone's effect, while the keys are closer to being flush and are flat rather than curved.

While many of the technical details aren't confirmed, the design is still expected to be a much more advanced replacement for the Sidekick 2008 and LX with a 480p widescreen, a 3.2-megapixel camera, 3G and GPS. When it will release still isn't clear, though Mobile World Congress next week is T-Mobile's first major opportunity to announce the upgrade.
