I currently have the iPhone 3GS (secondhand - handed down from a family member) but when I attempt to sync it with my iTunes, it says I need to download the newest version of iTunes. However I already have the newest version (or so I assume - iTunes 10 is the one I currently have downloaded - it says to download anything after 10.1 but I cannot seem to find it on the site). Any ideas as to why this happens? Help would be greatly appreciated!
