T-Mobile is said to be rolling out the Sidekick 4G this coming April 20th over at RadioShack, where this Samsung-manufactured device will feature the QWERTY keyboard that has long been a signature piece of hardware for its precedessors. T-Mobile has obviously moved on from the Danger operating system to Google’s Android 2.2 Froyo, and it remains to be seen whether there will be a Gingerbread update lined up sometime down the road or not. Apart from that, we do know that the Sidekick 4G will play nice with T-Mobile’s 4G network (obviously, by its naming convention), which is capable of a theoretical peak download speed of up to 21Mbps. Hardware-wise, the T-Mobile Sidekick 4G will come with a 3.5″ touchscreen display, a 1GHz Cortex A8 Hummingbird processor, and a VGA front-facing camera for T-Mobile Video Chat. Would you part with a Benjamin for the Sidekick 4G on a two-year contract?
