T-Mobile Sidekick 4G and G2x launching on April 20

T-Mobile confirmed today that its Samsung Sidekick 4G and LG G2x phones will be available in stores on April 20.

"It's official, T-Mobile's Sidekick 4G arrives on April 20," T-Mobile tweeted this morning. The G2x, meanwhile, will be available online on April 15 and in stores on April 20, T-Mobile also tweeted. It will sell for $199.99 after a $50 mail-in rebate and two-year contract.

T-Mobile confirmed plans for the Samsung Sidekick 4G back in January, and provided more details last month. It features a 3.5-inch, 800-by-480 screen and is based on a heavily customized Android 2.2.1 and Samsung's TouchWiz. The screen slides up with a click to reveal the 5-row QWERTY keyboard.

The Sidekick 4G is $149.99 with a two-year contract; you can get a $50 rebate if you sign up for a higher-priced data plan.

The G2x, meanwhile, was announced at this year's CTIA Wireless trade show—days after AT&T announced plans to acquire T-Mobile. But T-Mobile powered through, introducing the dual-core G2x phone and the G-Slate tablet, both from LG.

The LG G2x is T-Mobile's version of the very first dual-core mobile phone, the LG Optimus 2X. It has a 4-inch, 800-by-480 screen, and an 8-megapixel camera on the back. It will run Android Froyo, but will be upgraded soon to Gingerbread, according to T-Mobile.
