Last week, Apple decided to open iWork for iCloud to all users, but starting today, they’ve restricted the access due to an ‘overwhelming response’ to the service. The beta can be accessed via the standard iCloud page, and gives you a full access to a in-browser version of iWork, including Pages ( iPhone/iPad iTunes link ; Mac App Store link ) , Keynote ( iPhone/iPad iTunes link ; Mac App Store link ) and Numbers ( iPhone/iPad iTunes link ; Mac App Store link ).
