Yeah! Same here... It's like when I connect my Touch to the computer and open itunes, it just freezes and i have to click the close button all the time... It's really annoying. It just happened a couple of days ago.
You know something... My friend had like tried restarting his Ipod touch and since then he hasn't talked about it ever again... Do you think that restarting the touch fully will help it to connect again???
