For those looking to enhance the functionality of Wi-Fi on iOS devices, there’s a new jailbreak tweak for that. Dubbed BetterWiFi
by iOS developer Simon Selg, this new jailbreak tweak gives your iOS device a number of new features for discovering Wi-Fi networks, and seeing information about them.
Many of the tweak’s major features are shown above. The tweak lets you filter Wi-Fi networks so that you will only see open or unsecured networks in your Wi-Fi list, which might be useful if you’re traveling abroad and know that you won’t have the passwords to secured networks. This helps un-clutter the list and let you choose the unsecured Wi-Fi network of your choice. You can also view all of the Wi-Fi networks' security modes, as well as signal strength in dBm.
In addition, if you want to refresh your list, rather than exiting the Wi-Fi preferences pane and re-entering it, you can use Pull to Refresh to re-scan for nearby Wi-Fi networks:
Notably, the tweak will also let you remove the signal limit that Apple puts on Wi-Fi networks, which gives you the capability to connect to Wi-Fi networks that are even further away. Also, BetterWiFi lets you designate certain Wi-Fi networks as home networks, and will disable your device's passcode lock whenever you're connected to them so that you don't have to enter them when you know you're in a location where no one is going to snag your iOS device and start going through your information:
BetterWiFi adds a preferences pane to the Settings application where you can configure the tweak's various options. You will be able to enable or disable open network filtering, choose to enable or disable pull to refresh, configure smart passcode locking, choose to remove Apple's RSSI signal limitations, choose to display security types, and choose to display signal strengths:
BetterWiFi adds a lot of features to iOS to make using Wi-Fi easier and more informative. The tweak is compatible with iOS 6 devices including the iPhone, iPod touch, and iPad. If you want to give BetterWiFi a try, it's available in Cydia's BigBoss repository for $1.50.
