Here's a cool utility for Windows Mobile smartphones and PDAs, courtesy of the Microsoft-obsessed folks over at CoolSmartPhone. Pocket WiFi Radar is just that, a hotspot sniffer for your Wi-Fi enabled gadget.

The app costs $15. Pretty steep for the scrooges out there. But come to think of it, it makes mooching off free wifi connections that much easier. Who knows how much you'll save? Check maker Makayama's product page for a list of supported mobiles and handhelds.
