T-Mobile Sidekick 4G arriving on April 20?

The T-Mobile Sidekick 4G that was given a video preview earlier this week will be making its way to RadioShack beginning next month. According to a tweet for the official RadioShack account, we’ll be seeing the device in stores on April 20. Now since today is April 1, it might turn out to be a prank, but we don’t see any reason for T-Mobile/RadioShack to do such a thing – it’s just not funny or outrageous enough. The 3.5″ display Android 2.2 phone packs a 1GHz Cortex A8 Hummingbird processor, and will come preloaded with social apps such as Facebook and Twitter, and will also have access to features such as Cloud Text, Group Text, Samsung media hub as well as media room. No prices have been announced, but we should find out before it is released.
