Apple has taken the first step in opening the doors to its cloud computing service, iCloud.
Developers working on the system have been invited to transfer their MobileMe accounts into iCloud, 9 to 5 Mac reports.
The Mail, Contacts and Calendar sections port straight across, iWeb, iDisk and Photo Gallery will continue running until June 30, 2012, and various other MobileMe features including keychains and signatures will be suspended.
When it is launched, iCloud will enable users to manage their information from a hosted platform, automatically syncing that data, such as photos and music, across up to 10 different devices.
Apple has revealed that iCloud users will be offered 5GB of data hosting for free, with an additional 10GB of data costing US$20 per year, 20GB US$40 per year, and 50GB US$100 per year.
The service is scheduled to open to the general public in coming months.
