We all knew it was coming, but T-Mobile has just announced the Sidekick 4G,the successor to the insanely popular Sidekick. This time around it's made by Samsung, has a 3.5-inch capacitive touchscreen, powered by the Hummingbird CPU and Android 2.2. Add in a front facing camera, HSPA + network speeds up to 21 Mb/second, and a pretty faithful reproduction of the OG Sidekick's great five-row keyboard, and now it doesn't seem quite so tweeny.
On the software side T-Mobile is offering up two new messaging applications -- "Group Text" and "Cloud Text", Samsung's MediaHub, and a DriveSmart app which is designed to stop texting while driving. The addition of a dedicated app switching key, appropriately called the "jump key" looks pretty interesting as well. We have the full press release after the break, and the Sidekick 4G forums are open for business!
