Six years ago today the T-Mobile Sidekick was no longer available for sale. Any promotional material from t-mobile about the sidekick was removed.
In 2011 the Samsung branded T Mobile Sidekick 4G debuted to lack luster reviews. This sidekick was running Android OS and was heavily based on the Galaxy S phone. The device had a 3.2 megapixel camera and touch screen. The device was not a partnership with Danger the original maker of the Sidekick and was strictly just branded as a Sidekick. Microsoft held a big role in the Sidekick 4G as they purchased Danger, the original creator of the Sidekick. Microsoft used the Microsoft cloud to store Sidekick 4G data and servers and in 2011, shortly after the debut of the Sidekick 4G, Microsoft announced the closure of the DangerOS platform. This made all Sidekick models made before the SK4G unable to connect to the internet.
On April 15th, 2013 T-Mobile ceased sales of the Sidekick 4G. It is the last model of the Sidekick brand and the only model that can still be used today (if you’re okay with a super laggy experience and most of the apps not working anymore.)
