NetworkList list is a simple Cydia tweak that was released recently that allows you to find out the passwords to all the WiFi networks you have connected to. This is useful if you forget the password of a certain WiFi network, as you can simply check what it was the time connected your iOS device to it.
The tweak works by simply placing a new tab in the WiFi settings page called Known Networks. When you go into this tab you will be presented with a list of all the WiFi networks you have connected to and their passwords.
You can see the in the screenshot below a password to a WiFi network I connected to before on my iPhone 5.
That is all there is to this tweak. There are no settings to configure and no icons will be added to your homescreen. If you are interested in NetworkList you can find it in the BigBoss repo for free. Let us know what you think of it in the comments section below.
