RadioShack announced last week via Twitter that it is set to release T-Mobile’s new Samsung Sidekick 4G on April 20.Because T-Mobile has been mum about the details of the smartphone’s release date (the website says “coming soon”), RadioShack may have spilled the beans with its tweet. Regardless, fans now know they can get the new Sidekick in their hands before the end of the month.

Updates will include a touch screen on the panel and a front-facing camera with video call capabilities using the Qik Android app, Android 2.2 and a 1GHz Cortex A8 Hummingbird processor. Sidekick users will be able to download apps from the Android Market.

So … Sidekick? Or kick to the curb?
