If you want to quickly check what Wifi network you're connected to in iOS 9 then you should check new Cydia release dubbed as WiJoin. This jailbreak tweak displays a small popup in the bottom half of your jailbroken iPhone‘s screen any time your device connects to a different Wi-Fi network. The popup itself shows the name of the network you’ve just connected to, and it does so in a minimalist HUD.
How To Display Wifi Network You're Connected To On iPhone
To get started head Cydia’s BigBoss repository and download WiJoin tweak absolutely for free. Once installed the tweak will check what Wifi network you're connected to in iOS 9 and show it on your screen. The tweak works on all jailbroken iOS 7, 8, and 9 devices.
As you move from network to network, the popup will reappear each time and update you of the name of the network you’ve connected to in real time. As subtly as this small popup appears, it disappears after just a few moments. That being said, it shouldn’t ever really be in the way of what you’re doing.
This jailbreak can be useful when you’re in an area with multiple different Wi-Fi networks that your device is set to remember, such as while at work or when visiting someone else’s house. In this situation, your device will switch from network to network automatically, dropping the network with the poorer Wi-Fi signal for one with a better signal.
The big advantage of the tweak is that it quickly provides a way for you to know what Wi-Fi network you’re on at all times, as your iPhone switches. Usually you need to head to Settings > Wi-Fi to check this info that sometimes can be really annoying.
From the security point this tweak saves you from doing anything sensitive on your device until you connect to a secure network, something you can do easily when you’re informed of what network you’re on right now.
