The Wi-Fi Access HotSpot Directory at http://my.verizon.com/central/portlets/broadbandWiFi/hotSpotSearch.jsp is a great tool. But it's horrible to use from a smart phone. If you are out and looking for a wifi hotspot, the odds are you will be looking for it from a phone wth mobile Internet. If you view that page from an Android phone, it's sized as if it were accessed from a desktop browser. It's not hard to design a web app to render nicely in a mobile browser, especially for this app. It's pretty basic. With the current crop of mobile browsers, you can get the user's location. Make it simple, show me the hotspots close to my location.
Or do a simple Android/iOS app that does this. If you have an API for your hotspot locator, I'll write the thing myself.
