Why does apps on my iPhone keep crashing?

Hi when i turn of my jail broken iPhone and then turn it back on all the apps i downloaded from cydia crashes meaning that when i press an app it comes on the app then closes the app

Maybe the fact thats its jailbroken? Huge mistake seriously

This happened to me before, you have to update 1 app in the app store and they all start working again

Check your multitasking settings by double clicking the home screen button. This will allow you access to the multitasking user face. By holding the application in place for 3 seconds, it will give you the option to stop the application from running the background. Having multiple applications run in the background undetected will usually result in other applications crashing or failing to start.
