i have a problem with my ipod touch. as soon as i connect it to my imac usb it comes up on itunes The iPod “iPod touch” cannot be used because it requires a newer version of iTunes. Go to www.itunes.com to download the latest version of iTunes. I already have the latest version of itunes, my ipad works fine and recongnises my ipad but does not seem to work with my ipod touch, unable to put any content in it, it used to work but now that pop up mesage keeps appearing as soon as i connect it. any ideas? thanks in advance
