After you log into a Wi-Fi network on your iPhone, it will remember that network and connect to it automatically when in range. As you might come to expect, this means your handset keeps a database of previously used Wi-Fi networks. Unfortunately, Apple doesn’t allow users to access this information on their own devices out of the box.
If your iPhone is jailbroken, then you may be excited to learn that there’s a way around this frustrating quandary. A newly released and free jailbreak app dubbed WiFi List by iOS developer Itaybre consolidates all of your previously used Wi-Fi networks, their passwords, and more valuable information about them into one convenient place for future reference.
