When you're out and about, you can use a 3G signal to connect to the internet with your iPhone. But there are thousands of free wireless hotspots available all over the world which offer a significantly faster connection - but tracking them down can be difficult.

This is where Wi-Fi Finder can help. As the name would suggest, this free app makes it easy to find your nearest hotspot using your iPhone's built in GPS facility. With a directory comprising more than 280,000 hotspots in 140 countries, wherever you may be, the app should be able to find you a faster connection for free.

The program can be used in a number of ways. In GPS mode, the app will automatically display a map showing the nearest hotspots so you know where you need to go. But you also have the option of performing a search for hotspots in places other than your current location. This is handy if you are planning a trip and would like to plan where to stop off to get online.

The hotspot directory can also be downloaded so you can perform hotspot searches offline. This can be useful for occasions when you are travelling and do not have any sort of connection available - such as on a train. Any search results that are returned can be filtered by provider, type of location and whether they are free or not. A simple but handy tool.
