Iphone won't sync?

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?

 

it's alright everybody, you can all relax I've resolved it.

The problem was that I am too stupid for technology. And that I had accidentally set snitch to stop syncing

 

an application called little snitch was preventing itunes from linking to it's server.

I switched little snitch off just while i synced.
