It looks like T-Mobile’s Sidekick brand is growing up. The once-popular-with-teens slider phone is showing up as a more robust 4G device, made by Samsung now instead of Sharp, running on Android. These leaked shots show the device with the same iconic design, complete with the sliding screen and keyboard. This move makes sense as after Microsoft’s acquisition of Danger, maker of the Sidekick, T-Mobile maintained the right to use the Sidekick brand, which was especially popular with teens. Those teens are now more grown up and have more money to spend, so they’re likely to take note to this new release.
