I installed ios5 yesterday on my ipad, with backup to icloud selected. However it also wanted to backup my Goodreader files that were 2 1,8 gb large. I deselected the apps taking a lot of space on my ipad. Now my backup is around 40 mb, but the icloud manager still says I use half of my 5gb . How to fix? I thought it would disappear but it's stll hasnt changed.
