Jailbreaking your iOS device allows you to modify your lock screen, home screen and even the appearance of your apps and how they are arranged. WinterBoard is a popular tool that allows you to alter the look of your device by downloading themes to your iPhone from Cydia. There are themes to change everything, including your lock screen slider, your iPhone keypad and even your Wi-Fi icon. WinterBoard offers so many more possibilities than just downloading drab wallpapers.

CustomSiriBackground lets you spice up Siri's boring look by giving her the background of your choice. There are also several WinterBoard themes which can change Siri's icon into something more fun. My favorite is Siri9000, which transforms Siri into HAL 9000 from the film 2001: A Space Odyssey. You can even change the Siri start up sound into a few Hal quotes with a little advanced jailbreaking know-how.

My personal favorite jailbreak tweak of 2012 was SwipeSelection, and it's compatible with the evasi0n iOS 6 jailbreak. SwipeSelection is one of those tweaks you have to use to truly appreciate. It's a simple tweak that makes texting, taking notes and writing emails on your iPhone or iPad a lot much easier.

SwipeSelection allows users to drag one or two fingers across the keyboard of an iOS device to move the typing cursor. This makes editing text much easier by eliminating the need to tap the display of your device to delete or change letters. You can use one finger for a more precise cursor drag, or two fingers to move faster across the screen. You can also easily delete or copy entire sentences by holding the shift key and dragging your finger over the text you want to highlight. This is all demonstrated in the original concept video from Daniel Hooper posted below.

Looking for some great tweaks to get the most out of your iOS 6 jailbreak? Well if IntelliScreenX is Notification Center as it should be, then Auxo does the same for the app switcher. Auxo makes great improvements in the multitasking dock and takes advantage of the larger iPhone 5 display size.

The first thing you'll notice after installing Auxo is that each app in the switcher is displayed with a preview of its screen. Besides being aesthetically pleasing, these icons can be manipulated easily. Swipe one of the previews down and it's removed from the multitasking bar. Hold down on one and you will be prompted to remove all apps from the bar at once.

Now that you've jailbroken your iPhone 5 or another iOS device running iOS 6.0-6.1 it's time to install tweaks and customizations to get the most out of your jailbreak. IntelliScreenX 6 has the motto "the way iOS's lock screen should be" for a reason. The tweak has been in development for years and now brings a wealth of new features to the notification center.

First and foremost, IntelliScreenX makes it possible to quickly swipe down from the status bar when the device is locked and get access to current information. Of course, if you're worried about security you can disable this feature in Settings -> IntelliScreenX and still enjoy all of the enhancements to the Notification Center from the home screen.

Now that the evasi0n jailbreak has arrived, the software is proving to be the most popular jailbreak in history. Any iOS device running iOS 6.0 - 6.1 can be included in the fun with a few simple steps. Once the Cydia jailbreak app store is installed, free and paid packages can be downloaded to customize your device and add functionality.

For those who have jailbroken their pre-iOS 6 devices in the past, evasi0n brings even more convenience and simplicity to the jailbreak process. The software comes to us from the evad3rs, developers who have already released two updates to evasi0n to incorporate improvements and bug fixes.
