ok, there is a huge thread over on Apple.com's discussions page about all the different things people can *try* to make wifi work with the OS 3.0 upgrade. for those who don't know, or who are unaffected, a lot of people are experiencing broken wifi with the OS 3.0 upgrade for iPod Touch. many people are experiencing many differnet *workarounds* to accommodate apple's GHETTO OS 3.0 software update. that being said, this may or may not work for you. 1. Settings > General > Auto-Lock > Change to Never 2. Restart 3. You can turn Auto-Lock back on if you want. this has (finally!) enabled my wifi to work once again. for the curious, i'm not using a wireless router, rather my iMac's shared internet thru Airport.
