Apple has disclosed the pricing for iCloud storage and launched a limited beta version of iCloud for developers. Users of iCloud storage get the first 5 GB free, as stated when Cupertino announced iCloud in June. Additional storage will cost $2 per GB. Meanwhile, a preview of iCloud's suite of Web apps seems to be available for a select few developers. The iCloud apps run in the latest version of Safari on Mac OS X Lion. They include an address book, a calendar and a mail app, according to Darrell Etherington of GigaOm, who posted a screencast of the apps in action.
