In a big city with loads of Wi-Fi networks and struggling to find out
an open one? Now your iPhone helps you in that. Use the Setting Wi-Fi
dialog to connect to an open network.

The WiFinder app is here to help you:
1. It checks the local networks to see which are open.
2. It then attempts to connect to them and retrieve the web page of a
popular web browser.
3. If it manages to go through it flashes green check mark indicating
that it is safe to use.
The app catches those Wi-Fi with very low signal strengths, staffs
that generally Apple’s Wi-Fi settings do not catch.
