Apple has thrown open the virtual doors to its iCloud.com beta, allowing developers to get to grips with the MobileMe replacement. Devs can now sync contacts, calendars, mail, iWork and track their iPhone via iCloud.com.

The service itself isn’t due to launch until the release of iOS 5, widely expected to break out of beta in September. It comes alongside the new iCloud service, which will let Apple users store media in the cloud and sync it across different devices seamlessly.

On top of the beta release, Apple has also revealed iCloud storage costs for US punters. 10GB costs $20, 40GB $40 and 50GB $100. Users get 5GB free and stuff purchased from iTunes doesn’t count against storage space.
