Jailbroken iPhone not loading some apps?

Hey everyone, I got my iPhone 4 all jailbroken and whatnot. Just the other day it started doing this thing where some apps just won't load. Apps that sometimes have to load a little bit before they open, such as Mail, Messages, and Settings, they'll get stuck in that little loading bit for a minute or so, then just crash back to the home screen. Anyone have a solution for this? Thanks.

 

Let's see there was Move2Unlock, Remove Background, Mail Enhancer, Notified, and NotificationGriP. Those are the pretty recent ones.
