Since last night, my iPhone had started acting weirdly. Every 3rd party application that I attempted to use would start up and immediately shut down. The only applications that worked were the ones that came with the iPhone originally.
Most posts that I read prescribed that I wipe out the iPhone and reinstall everything – that would take too long and didnt sound like the way I wanted to spend my weekend. So on a whim I tried a couple of steps and voila! all applications began working again.
Here are those steps:
1. Perform a complete shut-down of the iPhone. (Hold the round button on the face and the power button on the top of the iPhone for a few seconds and the iPhone will perform a hard shut down).
2. Start up the iPhone.
3. Now install some new app that you dont have already on your iPhone.
4. Try opening one of the apps that wasnt working. (Cross your fingers, cause if it doesn't work – then you might be out of luck and might have to do a complete reinstall). If the app does work – then rejoice – you just kicked the iPhone back into behaving correctly.
