I bought an ipad 2 less than a month ago. It's only ever been connected to one PC (my home PC) which I authorized when I first synced. Yesterday, I had to do a full system recovery on my PC and reinstall itunes. When I went to sync again, it asked me to authorize the computer, so I did. Then it told me that I've authorized 3 out of the available 5 computers that I'm allowed. I can't understand this. Even if after the system recovery, the same PC counted as a 2nd time, I still should have only used 2 out of 5, not 3. Is there any way to fix this? Can I somehow remove authorized computers from my list?
