Once you're up and running, you can use the app to choose notification colours for certain apps and events, and even cycle through a series of colours if required. Vibration alerts and a special sleep mode can also be controlled by Light Flow.
7. App Icons
Get hold of App Icons for your iDevice and you can switch between customised themes of icons, as well as build your own for specific apps or links to websites.
You'll need to have the apps in question installed, and only certain apps are covered by the templates provided, but you can radically transform the look of your iOS device with just a few steps. If you don't want to have to shell out any cash straight away, you can pick up a free version of the app that contains ads.
Dropbox works across computers, mobiles and tablets and has become much more than a file-syncing and back-up tool. So how does it help you hack your phone?
It creates an intuitive, simple file system for your device, it enables you to easily install apps from outside of the official stores, it gives you more options when sharing and attaching files in other apps, and more besides. Whether you want to automatically back up your Photo Stream on iOS or install a beta app on Android, Dropbox can lend a hand.
Zedge comes packed with wallpapers, themes and ringtones you can apply on your Android or iOS device - it's all free to download and use, and new content is added on a regular basis.
On iOS you'll find yourself limited to wallpapers for your home screen and lock screen, but the Android version extends this to cover audio features too, including notification sounds and other types of alert as well as calls and text messages. You can set wallpapers to automatically change based on a preset schedule too, if you wish.
10. Apex Launcher
Another of the many app launchers available for Android, Apex Launcher is one of the most popular and well-respected in this particular bracket.
As well as a customisable grid size across nine separate home screens, you can hide apps and on-screen elements (like the Google search bar), add animations and transition effects, and play around with the theme engine that covers icons and wallpapers.
Upgrade to the £2.59 Pro version and you can access more advanced features (including unread count notifications) and additional gestures.
