Something weird started happening last night with my iPhone 3GS. My iPhone is on firmware version 3.0.1.
Out of the blue any app I launched just started crashing. They wouldn’t even try to open it. They will just crash within a second of tapping the app icon. All the native apps like Phone, Mail, Maps, etc worked fine but none of the other App Store apps.

If you experience this issue and start looking for help, the most common advice you might get is to restore your iPhone to factory settings and try installing apps again.
Before you try something drastic like that, try this quick tip.
Uninstall any one app from your iPhone. Install any app from App Store.
That’s it!
This little tip I came across in a forum worked like a treat. If your apps keep crashing on launch, try this quick tip and hopefully you don’t have to do anything dramatic.
