I JB my iPhone5 with Evasion the day it came out. Everything worked fine. A few days ago I restored to update to 6.1.2 (sadly we use exchange at work...) and then JB my device once again with Evasi0n 1.4. All went well. Since then, when I go in Settings>Brightness&Wallpapers>Wallpapers, my screen is black and I can't use any wallpapers. I've done the usual, Respring, Reboot, etc. I have not installed any new tweaks that could cause this. I've been using the same I was using before I updated to 6.1.2. Anyone else had this problem?
