A few years back, Sidekicks were all the rage for the tweens and teens. Few devices at that time had the loyal following like the Sidekick brand endured, but fast forward a few years and add in a couple new mobile platforms, and the Sidekick is about to be punted into history.
T-Mobile has announced that, as of May 31, "Microsofts Danger Service, which is used to provide cloud data services to T-Mobile Sidekick users, will no longer be available," according to Mobileburn.com. For those who use the service, T-Mobile will be providing offers to all current users and will also be publishing a web tool to export the customers data. The tool will be able to export all of your data which will help make the transition a bit more palatable.
The Sidekick brand has been slowly been removed from the marketplace as the hardware is now outdated and faces many rivals including Android. For those still using the platform, your days are unfortunately numbered, but if you need some comforting, find a KIN user and ask them for advice.
