Once you've gone inverted, it's hard to go back to black text on a white background. Of course, applying this theme of altered colours is easier in some places than others, with Apple devices being one of the more trickier propositions. Fortunately for those with jailbroken gadgets running iOS 7, there's a pay-for option that will do a decent job of darkening your mobile experience.

Android (rooted): Today, the developers behind Cydia and Mobile Substrate announced that Cydia Substrate will be coming to Android. You read that right: Cydia on Android. In fact, Winterboard is already available.

The iPhone has a beautiful home screen, but it looks the same as every other iPhone out there. If you want a phone that's truly yours, here's how to customise the look of your home screen from top to bottom.

The jailbreak for iOS 6.1 just arrived, but Apple had to quickly introduce two emergency patches to the OS to fix Exchange support and a lock screen privacy bug. Thankfully, you can still jailbreak the updates, but if you're already running iOS 6.1 you might not want to hunt down your apps and tweaks again. Here's how to make it a little easier on yourself.

I recently jailbroke my iPhone and now that it's done I'm very overwhelmed by Cydia. I've downloaded a couple apps, but I don't understand most of what I'm looking at. The descriptions and explanation in Cydia don't help much, so I'm wondering: can you help me wrap my head all this stuff?

iOS (jailbreak): Orbit is a handy jailbreak hack that adds home screen page switching in the style of Mac OS X's Expose feature. This is very useful if you've got a lot of apps and pages to manage.

iPhone 4S (Jailbroken): The voice-assistant Siri is pretty useful on the iPhone 4S, but there are a lot of things you still can't do with it. This Cydia tweak will cross a few items off that list, including turning on or off wireless settings, setting your screen brightness and reading your battery level back to you.

iOS (Jailbroken): Apparently, Apple was testing a panorama mode feature for the iOS 5 camera, only to leave it in test mode for the actual release. All you have to do to enable it is to jailbreak your phone (instructions here), then find the Firebreak app in Cydia. Once installed, just follow the on-screen instructions to make a panorama picture.

Apple likes to verify software updates, which is not so good for your jailbroken iDevice. Cydia generally circumvents the problem, but its servers aren't exactly working at the moment. To avoid problems, you need to back up something known as your SHSH file. Here's how to do it.
