Apple yesterday went live with a developer beta website for its new iCloud offering. The site currently features web apps that include Calendar, Find My iPhone, iWork, Mail and Contacts.

This is the latest portion of iCloud to be released. End users have been able to test limited portions of the product on devices running iOS 5 and OS X Lion since it was announced back in June.

Apple confirmed to Electronista that it will be offering 5GB of data on iCloud for free (photos and music don’t count toward that storage), with additional storage running at $20 for 10 GB, $40 for 20 GB  and $100 for 50 GB.

When launched, Apple’s iCloud will integrate all of the company’s services, including iTunes, which will allow users to download previously purchased iTunes music to iOS devices. Also, the company will roll out iTunes Match, which will allow users to match their music not bought on iTunes with Apple’s catalog for an annual fee of $24.99.

iCloud also will include a Photo Stream service, which automatically uploads the photos a user takes on an iOS device and wirelessly pushes them to all of the user’s devices and computers.
