Frankly, none of the Wi-Fi hot spot finder iPhone apps I've tried do a consistently fantastic job. But ($2) is fairly comprehensive and relatively up-to-date, which is more than I can say for .

Both apps use your current GPS location to show you a list of nearby hot spots. Of course, you can get this information just by opening your iPhone's Settings, clicking Wi-Fi, and viewing the list of available networks. However, WiFi Directory also shows you at a glance which nearby Wi-Fi hot spots are free, which is the main reason why I rely on this app when sniffing out a wireless connection on the go.

I've become addicted to falling asleep to white noise. It's soothing, and it blocks out ambient sounds. I'm especially in need of my white noise when on a plane (I've got to block the sounds of the inevitable screeching toddler) or staying in a hotel. The free does the trick for me.
