It is an online service with a companion mobile client application from Microsoft. The service, which launched on October 6, 2009, provides a free mobile phone back-up solution by wirelessly synchronizing contacts, calendar appointments, tasks, text messages, browser favorites, photos, music, video and documents with a password-protected online portal where users can access and manage their information. The service also enables photo sharing and, in some markets, a set of features for dealing with a lost phone that are sold as a Premium Package requiring a one-time fee. My Phone supports Windows Mobile OS versions 6.0, 6.1 and 6.5 and is available globally in 25 languages. The service uses Windows Live ID for authentication and the Windows Live server infrastructure for storing user information. On June 8, 2011, Microsoft announced that My Phone would be discontinued with sync from phones ending on August 7, 2011 and website access to data ending on October 6, 2011. Data (Contacts, calendar entries, text messages and photos) will be moved to SkyDrive.
