Apple has just released Mac OS X Lion 10.7.2 Update Build 11C40, iCloud for OS X Lion beta 8, and Safari 5.1.1 Update 2 to developers.
iCloud Storage APIs enable your apps to store documents and key value data in iCloud. iCloud will wirelessly push documents to a user’s device automatically and update the documents when changed on any device — automatically.
In order to get the three pieces of software above, you must be a registered Apple developer. A developer registration, which will set you back $99 per year, gives all subscribers access to exclusive pre-release software as well as developer-oriented tools and documentation.
