T-Mobile Sidekick 3T-Mobile has announced the death of Danger, the cloud-data service that powered the original line of Sidekick phones starting in 2002. What many people may not realize, is that most of the functionality of the Sidekick (outside of making calls and sending texts) required the device to be connected to Danger servers. By getting rid of Danger, all of the Sidekicks that use it are relatively useless.

Danger was purchased by Microsoft in 2008. Microsoft attempted to revive the service with its line of Kin phones. The Kin, however, was a huge disappointment for the company, making it not entirely surprising that it would choose to shut the service down.

The service will be officially cut off on May 31. T-Mobile said in its statement:

T-Mobile will provide offers for our Sidekick customers before May 31, 2011, to help make an easy transition from their existing Sidekick device to a new device. We will have more information to share about these offers with our customers in the weeks ahead.

To ensure the best possible transition for our loyal Sidekick customers, an enhanced Web tool is available on myT-Mobile.com to easily export their personal data, including contacts, photos, calendar, notes, to-do lists, and bookmarks, from the Danger service to a new device, computer, or a designated e-mail account.  An application is also available in the Sidekick Catalog to make it easy to export personal data to the Sidekick's memory card.  Many T-Mobile stores can transfer data from that card to a new T-Mobile device if the customer brings in the memory card and Sidekick.

A new 4G Android-powered version of the Sidekick is expected to be released on T-Mobile during the first part of this year. It's possible that the May 31 deadline is to ensure that the new Sidekick is out, so that long-time fans can make a smooth transition to a similar device.

Anyone currently using the Danger service? Anyone else already think the service was dead?
