Help! Cydia, iFile, and MyWi are all crashing on me. The strange thing is that on a respring, one app works ONCE. Then after that, none of them work. For example, I run Cydia and then shut it down. After that, Cydia, iFile, MyWi all do not work. They get about 1 second into the start up and then go down.

I've tried reinstalling Cydia but no go. I've tried the various online solutions about cleaning up /private/var/lib/apt/lists and couple of other places. No go.

This is what I get in cydia.log:
/Applications/Cydia.app/Cydia: line 6: //Applications/Cydia.app/Cydia_: Operation not supported
/Applications/Cydia.app/Cydia: line 6: //Applications/Cydia.app/Cydia_: Unknown error: 0
/Applications/Cydia.app/Cydia: line 6: //Applications/Cydia.app/Cydia_: Operation not supported
/Applications/Cydia.app/Cydia: line 6: //Applications/Cydia.app/Cydia_: Unknown error: 0

In MobileSubstrate safe mode, everything works just fine.

My question: what do these apps share in common and how can I fix it??

Thanks.
