I have a MBP with OS X Lion. I downloaded the X.2 update, updated iTunes, downloaded the iCloud update. I've signed in with my Apple ID, and checked everything, enabled Photo Stream etc. However, it still tells me that 5gb of 5gb is available, and when I click on the manage button to the right of the storage bar, it says "You are not using any iCloud storage" as well as saying Mail 0KB and Backups 0KB. What am I doing wrong? I have not yet upgraded my iPhone 4 to iOS5 and won't be doing so until I know that iOS5 doesn't have any major bugs. Plus I'm going away for a week so won't get a chance to do that until after I get back. Do I need to have an iOS5 device before it will start to backup? Or should it be backing up my data from my MacBook Pro already?
