In a previous guide, I showed you how to add a 5th app to your icon dock. This is both useful and cool-looking.
Unfortunately, cramming a 6th would be make the tapping area too small, so instead I'll show you how to save space by making your most used app easily accessible with a simple swiping gesture.
It may sound intimidating, but jailbreaking is really simple. Just follow our guide on how to jailbreak your iOS 7 iPhone.
After jailbreaking, open the pre-installed Cydia app, and search for and install Fav.
Go into your Settings app, locate Fav, choose the app you'd like to easily access with a swipe, and then enable.
Enabling the App Icon or App Snapshot options will dictate the view as you swipe your favorite app in from the left side of your first home screen, as seen below.
Have fun with this quick tweak, and remember to checkout the iOS hack page for more awesome tweaks.
