How to Fix App Crashes on iPhone 4 iOS 4.3.3?

Hi, I have an iPhone 3GS it is jailbroken on iOS 4.2.1. Last month, I asked my daughter to upgrade it to the latest firmware and she said she restored it to iOS 4.3.3 and then rejailbreak it using Redsn0w. However, after a week, I’ve noticed that some of my apps were crashing (mostly App Store apps) after upgrading it to the latest Apple firmware. How can I fix this? Do I need to rejailbreak or remove the jailbreak of my iPhone? Thanks.

Hello Josephine, well, there are numerous procedures on how to fix this error and it can be fixed in an instant. To fix this error, just simply hard reset your iPhone and then fire up App Store apps and download and install any free apps available. Restart your iPhone once downloaded and installed. Or, if your apps still crashes, you can try to put your iPhone into DFU mode. Some of our readers who have experienced this error on their device after restoring it to new firmware that putting your iPhone (iPad or iPod Touch) into DFU mode will fix the error. To put your iPhone into DFU mode, all you have to do is connect your iPhone into your Mac or PC via USB cable. Then just simply hold down home and power button for 10 seconds. This will make your iPhone’s screen go blank and it will switch off like a vintage TV. After 10 seconds, release the power button but keep pressing the home button until your PC produces a beep sound and iTunes will prompt you that it has detected your iPhone from recovery mode.

Lastly, to make sure that there’s no error, you can restore your iPhone to stock iOS 4.3.3 and then rejailbreak it using Redsn0w 0.9.6rc16 that is available for both Mac OS X and windows. Hope this helps!
