How to Reformat & Remove Jailbreak from iPhone 4?

Hi guys, I just recently bought a pre-owned iPhone 4 from eBay. I can say that it works absolutely fine and still in very good condition. Additionally, it has numerous apps installed. The device is running on iOS 4.3.3 and it is jailbroken. However, I want to reformat it to remove some of the jailbreak apps installed. Some of them are useless, I think. And some of them are quite unresponsive. I want to delete them completely. Can anyone tell me how to completely remove the jailbreak from my iPhone? Cheers.

Hello Paul, are you sure that you want to completely remove the jailbreak from your iOS device? Because if you do, then you will not only lose the jailbreak of your device, but as well as your installed iTunes apps, include your settings, saved photos, videos, emails, etc…

Anyway, I would recommend you to backup your SHSH Blobs using iFaith SHSH Dumper so that you will be able to downgrade your iPhone iOS 4.3.5 (the latest version of iPhone firmware) back to iOS 4.3.3 and then re-jailbreak in case you want. As well as sync your iPhone to iTunes before restoring it to the recent iPhone firmware. Once completely synced with iOS 4.3.3 SHSH Blobs saved, then connect your iPhone to iTunes via USB cable, select your device, navigate to Summary tab and Restore your device. (Additionally, if you want to re-jailbreak, just downgrade your device back to iOS 4.3.3 using the save SHSH Blobs via TinyUmbrella, an then jailbreak it using JailbreakMe 3.0)

Alternatively, if you are having issues with just a single app, then you can delete that specific app or just update it. You can look for Cydia for all updates under Changes tab. The same thing applies with iTunes app. You can easily update via iTunes.
