Danger is dead. Long live Sidekick. T-Mobile just made the Sidekick 4G official, though they didn’t include a price or ship date with the press release and photo sent out tonight. Grr.

Sidekick 4G is made by Samsung, based on Android 2.2, and features a 3.5-inch touchscreen and compatibility with T-Mo’s 4G  network (HSPA+ 21 Mbps). The device looks like a Sidekick, has a crazy pop-tilt swivel mechanism like a Sidekick, and boasts a very Sidekick-looking five-row QWERTY keyboard. New to SK4G are CloudText and GroupText, which I’ll let T-Mobile’s PR people describe to you:

Sidekick’s Group Text feature lets customers create, name, manage and participate in reply-all group text conversations, enabling them to lead their network in conversation and social planning. Group Text breathes new life into one of the most popular forms of messaging allowing Sidekick 4G customers to initiate and share the benefit of the application with SMS-capable devices from flip phones to smartphones. In addition, Cloud Text provides the option to text with friends or groups across platforms, whether from the comfort of their PC’s large screen and keyboard, or from their new Sidekick 4G.

You’ll also get pre-installed Facebook and Twitter apps, and access to a bunch of free and paid media services out of the box, including Slacker Radio, T-Mobile TV, YouTube and Samsung Media Hub. A 1GHz Cortex A8 Hummingbird processor makes SK4G sing, and I’d personally like to thank T-Mobile for including something called DriveSmart on the device. Best I can tell from the press release, DriveSmart fields all incoming calls and texts while its Sidekick’s owner is behind the wheel, automatically replying with a customizable message along the lines of, “I’m driving. I’ll call you back when doing so won’t endanger me, my passengers, and that dude next to me in the Infiniti.”

Sidekick 4G will be available in matte black and pearl magenta when it launches “later this Spring.” In the meantime, drool over the official press photo up top and the purported “in the wild” shot below, originally posted on TmoNews back in late January.
