MobileMe (formerly .Mac and iTools) is a subscription-based collection of online services and software offered by Apple Inc.. All services are being gradually transitioned and/or replaced by iCloud and the service will cease as of June 30, 2012.
Originally launched on January 5, 2000, as iTools, a free collection of Internet-based services for users of Mac OS 9, Apple relaunched it as .Mac on July 17, 2002, when it became a paid subscription service primarily designed for users of Mac OS X. Apple relaunched the service again as MobileMe at WWDC 2008 on July 9, 2008, now targeting Mac OS X, Windows, iPad, iPhone, and iPod touch users.
On February 24, 2011, Apple discontinued offering MobileMe at its retail stores. MobileMe retail boxes are also no longer offered through resellers. Additionally, Apple is also no longer accepting new subscribers for MobileMe. At the iPhone special event on October 4, 2011, Apple announced it would launch iCloud on October 12, 2011, to replace MobileMe for new users. MobileMe will continue to function until June 30, 2012, at which point the service will no longer be available. MobileMe users are encouraged to migrate to iCloud before then.
