Apps open then immediately close?

[CMW3762]

Hi there,

I have an iPhone 4 on 5.0.1

I jailbroke my device and everything has been working fine, however not, when i open things such as safari and mail, they close immediately and return me to the home screen.

I have tried soft reset, to no avail. Don't wanna restore because it will take me to 5.1.

Things i have installed recently:

Cascade
Infidock
My3G

i have since removed these and they still dont work. Any advice?

I found the problem. There seems to be something wrong with 'My3G'. after uninstalling it everything is working fine
