On a short note, the iPhone app Free WiFi Finder locates internet wireless hotspots around the world, displaying those closest to you. The app uses your GPS integrated function to locate and display various access points from over 10,000 locations worldwide available in its database.
The app gives you the possibility to search for hotspots based on your current geographical location, filter the results by location type (cafe, library, restaurant) and display the desired results complete with phone numbers and address information for every hotspot location. Browse through your locations and bookmark your favorites.
