Every time I try to sync, I get "Could not complete your Itunes store request. Unknown error (-9807).There was an error in the iTunes Store. It's been unable to sync for a few days now. Everything else seems to be working. I can link to the itunes store in iTunes, I can download apps from my phone etc. Any ideas on what the problem is or how I get round it? Whats the normal proceedure? reset phone?
