Okay, so heres the deal. The other week, I was downloading some apps, like normal. When they were finished I went to open the app store, but it froze, so I rebooted my iPhone. When it turned back on, I went to try an app, and it crashed and closed. So I tried another. Crashed and closed. Another. Crashed and closed. Now none of my apps are working at all - all just crash and take me to the home screen. I haven't been able to find a fix for this as yet and its starting to become very frustrating. All the normal apps work (calendar, maps, stocks etc) but not 3rd party ones. I don't particually want to delete all of them either as I have 116 apps and it would take forever. Help me, please!
