MobileMe (branded iTools between 2000 and 2002; .Mac until 2008) is a discontinued subscription-based collection of online services and software offered by Apple Inc. All services were gradually transitioned to and eventually replaced by the free iCloud, and MobileMe ceased on June 30, 2012, with transfers to iCloud being available until July 31, 2012, or data being available for download until that date, when the site finally closed completely. On that date all data was deleted, and email addresses of accounts not transferred to iCloud were marked as unused.
Originally launched on January 5, 2000, as iTools, a free collection of Internet-based services for Mac OS 9 users, Apple relaunched it as .Mac on July 17, 2002, when it became a paid subscription service primarily designed for Mac OS X users. Apple relaunched the service again as MobileMe on July 9, 2008, now targeting Mac OS X, Microsoft Windows, iPhone, and iPod Touch users.
On February 24, 2011, Apple discontinued offering MobileMe at its retail stores, and later from resellers. New subscriptions were also stopped. On October 12, 2011, Apple launched iCloud to replace MobileMe for new users, with current users having access until June 30, 2012, when the service was to cease.
iTools and .Mac were designed primarily to provide Internet services for Mac owners. All members of iTools and .Mac received a @mac.com email address, showing the services tied to the Mac hardware. However, with the release of the iPhone 3G in 2008, the renamed service, MobileMe, began providing Internet services for OS X, iOS, and Windows. Members of MobileMe were given a @me.com email address (though users of the current @mac.com email address could also continue to use those, with both domains being interchangeable with the same email account), were also no longer restricted to OS X software such as Mail and iCal, and they could access personal data from any computer connected to the Internet using the web interface at me.com or a number of supported applications, including Microsoft Outlook, as long as the user used version 2003 or later.
