Here's some great iPod Touch websites to check out:
Appminute.com - Check this site out for videos of iPod apps. (A little disclaimer: I write for this site's sister site MyMac.com) You can also search for AppMinute in the iTunes store for the Appminute Podcast. If you like short and to the point podcasts, you'll like the AppMinute podcast.
Toucharcade.com - A great site for iPod Touch gaming news and reviews. Want to see upcoming releases for the iOS platform? This site has a lot of sneak peeks.
iPhoneAlley.com - The name says iPhone, but you can find iPod Touch news here also.
macrumors.com/iphone - This is the MacRumors sister site for iPhone and iPod Touch news. Once again, the name says iPhone, but the iPod Touch is covered also.
There are a lot of iPod Touch themed podcasts out there, as well as Mac themed podcasts that cover the iPod Touch.
One final tip: Play around with the Settings application. You never know what you might find. That is what I do, and I often find features I never knew existed.
So there you go, some more tips for your iPod Touch. If it turns out I forgot enough for a third article, I guess I'll have a trilogy!
