iPod touch Safari keeps crashing!?

I jailbroke my ipod touch about two months ago. It had no problems untill the last two weeks when my safari app keeps crashing when im using it. Sometimes when listening to music, and also when im not. Could someone tell me why this is doing this and any solutions to the problem.

The list of apps on my ipod are:
All the iphone apps
Customize
SMBPrefs
Lockbox
TTR

I have plently of room on the ipod like a gig or so. So it can't be a storage problem?

that's what i was thinking. I just don't really feel like jailbraking it again. You know?
