WiFiFoFum
There's a new free software app for finding WiFi hotspots for Pocket PCs called WiFiFoFum that besides just listing the name and signal strength of every nearby wireless access point actually sows the relative location of each of them on a radar-type screen. Every time we ever write about those keychain WiFi detectors someone always writes in to complain about how the little gadgets can only tell you if you're in the presence of WiFi, and really not much more than that. If we can be bothered to write back, we usually tell them that you can't expect more out of a $20 tchotchke and that they need to invest in a wireless PDA with something like WiFiFoFum installed on it.
