T-Mobile USA announced the impending termination of its cloud-based Danger services. Danger is a subsidiary of Microsoft, which was instrumental in creating the Sidekick devices, which store content on the cloud.

According to a statement from T-Mobile, the services will officially be terminated May 31, 2011.

T-Mobile says it will provide offers for 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,” read the statement.

T-Mobile is making “an enhanced Web tool” on its website for customers to 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.

The company said an application is also available in the Sidekick Catalog to make it easy to export personal data to the Sidekick’s memory card. The company’s retail locations can then transfer data from the card to a new T-Mobile device if the customer brings in the memory card and Sidekick phone.

This will be the second cloud service engineered in part by Danger that has been shut down. The company also was instrumental in the creation of the Kin One and Two devices, as well as the corresponding Kin Studio service, which Verizon Wireless officially discontinued on Jan 31, 2011.
