So my macbook's hard drive died and I had it replaced. I used an external hard drive to transfer my old library back onto the new hard drive.

When I try and sync my iphone, itunes prompts with a message saying there are apps that are on my iphone that aren't on the computer and would I like to transfer these to the computer.

After I click on yes, it tells me this computer isn't authorised for this account. Then it gives a new message saying I have already authorised this computer. After clicking ok, it then gives me the first message again and wants me to authorise the computer..... an endless loop.

I have tried restarting both items, deauthorising and reauthorising all to no avail. Any ideas?
 
It seems like you've done all you can (e.g., you reauthorized), so just restore the phone and resync.
