Vestigo cydia tweak allows you quick access to the list of available WiFi Networks and to quickly change to another.
It integrates perfectly in iOS with his UI and his simplicity of use.
Vestigo is not only a simple “WiFi selector”, it gives you the ability to know everything you have to know about your nearby WiFi networks.
Tapping on the info (I) button on the top right of his interface, you can see all your known networks and the respective saved password.
So, if you want to share your “forgotten” WiFi password to a friend of you or a member of your family, you can simple launch Vestigo and search for your password in “Known Networks” list.
Vestigo will works with Activator, so you can use different gesture to launch it.
