iLock isn't on that list, nor does it work. When you try to install it from Cydia, it reboots into Safe Mode, and never leaves it (after restarting) until you uninstall it from Cydia. In the meantime, any suggested alternatives? I bought iLock on 4.3.x so I didn't exactly waste money, but I'd like to modify my lockscreen until iLock works again.
