How to Fix Camera Issue on Jailbroken iPhone 4 Without Restoring?

Hello Arnel, I think some of the apps, which includes both App Store and Cydia apps are conflicting with the native iOS camera app of your iPhone. Therefore, I would recommend you to update them through Cydia or iTunes or just uninstall them completely. You can also download an app called Crash Reporter to help you determine which apps giving you a headache. Crash Reporter can be downloaded from Cydia Store via BigBoss Repository.

If the above tips don’t work, then the only way to fix this error is through restoring your iPhone. Well, you don’t have to worry about restoring your iPhone especially if you have saved iOS 4.3.3 SHSH blobs. Since your wife’s iPhone is jailbroken, there are chances that Cydia might have already saved the SHSH blobs of the device. You can check this tutorial to see if you have saved SHSH blobs. If you do have saved SHSH blobs, go ahead and restore your iPhone to iOS 4.3.5 and then downgrade it back to iOS 4.3.3 using the same TinyUmbrella tutorial.

If you don’t have saved SHSH blobs, you can use iFaith SHSH Blobs Dumper to create your own blobs. You can refer on this guide on how to use iFaith to backup your SHSH blobs. Once you have your SHSH blobs, you can follow this tutorial on how to create a signed IPSW file (Create iOS 4.3.3 firmware) using iFaith as well, which you can restore on your device.

After restoring / downgrading your iPhone just simply rejailbreak it on iOS 4.3.3 with Redsn0w 0.9.6RC16 and then unlock it with your Gevey SIM.
