I have just received my iphone and am unable to sync it with my pc through itunes. Does anyone else have a problem with this?? My iphone has been unlocked to all networks. Is there a specefic version of itunes you need for the iphone to sync?

Also, within the downloads section of this website, referring to themes, how do I get the download I want from the website (downloaded onto desktop) onto my iphone?

Thanks.
