hi, i brought my ipod touch today, i have got home and plugged it into my laptop with my previously installed itunes which i used for my video ipod, as said in the instructions i plug it in. The itouch is recognised as a camera on my computer and isnt recognisable on itunes???? why is this? it says in the quick set up guide to plug it in and then the prompts will follow on the touch screen but all i get on the touch is the picture saying plug it in...??!! please help me i am desperate to get my itouch going haha!
