Auxo – A refreshing, altogether better take on the current iOS multitasking situation. It offers a preview of your app’s current state, and while this is useful in itself, it also looks a great stretch better than the stock offering.
Octopus Keyboard – This tweak brings the BlackBerry 10 keyboard to jailbroken iOS devices. You’ve seen the previews and the demo videos of BB10 in action, and if the keyboard takes your fancy, this tweak is one for you to consider.
SBSettings – SBSettings is, many would say, the most useful tweak on the cydia store. If you have jailbroken before, you’ll already be more than aware of its capabilities, but for the uninitiated; SBSettings provides an easily accessible menu of all your device’s key functions in any one place. Once activated, one can toggle Wi-Fi, 3G, Data, Location Services, Brightness, Airplane mode, and other features on / off with a simple tap, as well respring / reboot / lock / safe mode or power off with absolute ease. Oh Apple, please make this a native feature!
WinterBoard – Created by Saurik, this is the original theming app for iOS. WinterBoard differs somewhat from Springtomize in that it focuses on the overall look of the lock screen and home screen. If you don’t feel like theming yourself, there are trillions of pre-made themes available online and through Cydia, so there’s bound to be a look to suit you. Oh and if you decide to install WinterBoard, make sure you try Ayecon theme, it is by far the best theme available for jailbroken devices.
App Locker – Pretty self-explanatory, App Locker allows you to lock your apps with a password. This is especially useful if you don’t want to unlock your device every time you use it, but want to keep certain apps closed from prying eyes.
Zeppelin – This allows you to change your carrier logo / text to an icon of your desire.
f.lux – f.lux is a truly unique app which brings a warmer, ‘sunset’ overlay to your device’s screen. It’s certainly one that has to be experienced to be appreciated, and you can also set it to activate only at night, which is useful since it’s easier on your eyes.
