Connection issues with iPod touch I have one year old iPod Touch. All of a sudden YouTube is not working. I have wireless network at home.

It says "Cannot connect to YouTube". I'm also facing this issue when I connect to Gmail. it says - "Cannot connect to imap...". but still I can see my mail.

I guess it shouldn't be issues with wireless or n/w connectivity because Safari browsing is working fine.
I had a similar issue for a few weeks.  I found that the problem was with my firewall.  Even though I had told the firewall to allow all traffic to and from my ipod, it still didn't work because the firewall slowed down the internet tremendously.
