T-Mobile announced that it will bring back a revamped version of the iconic mobile phone, the Sidekick sometime this summer.

The new Sidekick 4G, built by Samsung, will operate on Android 2.2 OS and feature the same design and texting capabilities ,such as the large slide out Qwerty keyboard and the pop tilt hinge, that made the phone a hit with the younger crowd.

“There are a few key elements of the device that really do make it a Sidekick in the minds of customers,” T-Mobile product manager Joe Fernandez said told PCmag. “One is just the design … in second place is the UI, and it’s always been known as a killer messaging device,” he added.

The Sidekick has a 3.5 inch WVGA touch screen when closed, a front-facing VGA camera for video calls, and a 1GHz Hummingbird processor. Since the phone runs on Android, it allows for easy access to the Android app market, and features a jump key that makes for quick multitasking and going back and forth between apps. It will also have access to T-Mobile 4G network.

Since the appeal of the Sidekick weighs heavily on its social aspect, Facebook, Twitter, and Qik video chat come preloaded and text messaging is given a new dimension with cloud text features and group text, reports Cnet.

“We’ve reinvented the messaging experience that made the Sidekick such an iconic device, and supercharged it with communication and entertainment experiences that take full advantage of our 4G network,” said Andrew Sherrard, senior VP of T-Mobile product management in a press release relayed by CNN.

On his end, Samsung’s President Dale Sohn said he was proud that T-Mobile chose his company to take the Sidekick to the next level and added in the press release, “Samsung redesigned the new Sidekick 4G with our best-in-class hardware, combined with T-Mobile’s 4G network speeds, the Android operating system, and unique messaging and entertainment features, to make this a perfect match for both loyal Sidekick fans and new Sidekick owners.”
