Just curious as to why you don't update to iOS 6 or whatever the iPhone 4 goes up to and do an untethered jb ?

Sounds like it doesn't play well with whatever you just installed. Hold the volume-up button while booting, this will disable MobileSubstrate (and, hopefully the tweak), allowing you to open cydia and uninstall the offending tweak.

For best results, please include information about your device, including its iOS version and what type of device it is, plus the repos and tweaks installed. Also, please don't hijack old questions, start your own.
