An iPod-based Guide To SF Wireless Hotspots
Ryan MacCarthy writes "On the day Apple announces the 4G iPod, BayAreaFreeFi.com announces the wiPod , an iPod-based field guide for free wi-fi hotspots in the San Francisco Bay Area.
Now when you are on the road you can look up a free hotspot quickly and easily right from your iPod. No, the iPod isn't wi-fi enabled. wiPod uses the Notes functionality of the iPod OS to store the database in an easy to use format.
Enjoy!"
While not iPod friendly, I found this website when looking for hotspots in the Kansas City area: www.jiwire.com.
They claim to have nearly 47000 hotspots in 65 countries, 15000 in the US. I hope this helps some.
