iCloud is a cloud-based storage platform where you can store music, photos, apps, calendars, documents and more for free, associated with a person’s Apple ID account, and pushes it to all their iOS devices.

Users who have developer accounts and are running in iOS 5 or OS X 10.7 can check out the new iCloud Web apps, which include Mail, Address Book/Contacts, Calendar, “Find My Phone” and the iWork suite, Venturebeat reports.

Apple has released the yearly pricing model for iCloud services. Every user will get 5 gigabytes of free storage. The company will charge $20 a year for 10 GB storage, $40 a year for 20 GB and $100 a year for 50 GB.

“MobileMe Web apps are currently blocked from iOS mobile users, apparently because Apple's mobile browser does not support the 'real Web' well enough to work acceptably with them. This prevents iOS users from accessing a secondary account,” AppleInsider reports.

Smartphones and Tablets running on Android and other mobile users are similarly blocked from accessing MobileMe, and get the same "download the iOS native apps" message iOS users get, despite there being no MobileMe native apps that Android or other mobile users can install.
