DeepEnd is a cool little jailbreak tweak which adds a 3D effect to your iPhone 4′s homescreen wallpaper. DeepEnd was coded by well known developer Ryan Petri.

DeepEnd works by using your iPhone 4′s gyroscope to change your iPhone’s screen orientation based on the angle you hold your device, creating a 3D effect to your homescreen wallpaper! Remember, you will need a jailbroken iPhone 4 or other supported iDevice in order to install this!!

You may be asking, “What’s the big deal about this tweak?” Well, it makes a 3D effect on your homescreen wallpaper (which, in my opinion, is pretty cool) and….. it’s free! Download it in Cydia by adding the following repo to your sources:  http://rpetri.ch/repo/
