Let’s face it, iOS 5 is stupendous, it’s game changing, and it’s leaps and bounds over a stock iOS 4.3.3 installation.
Unfortunately, it does feature two primary caveats. First, you can’t jailbreak your iPhone running iOS 5 just yet, because there is no official tool to do so. Secondly, it can be mighty slow and buggy at times.
The latter was a complete deal breaker for me, and of course since you can’t jailbreak just yet, I decided to head back down to iOS 4.3.3 on my iPhone 4.

The only problem with that decision is that it isn’t as straight forward as one would like it to be. I was met with an iTunes error (1) recovery loop while trying to downgrade to iOS 4.3.3. Sadly the screenshots I took of the error were lost, so I don’t have those available.

That being said, you can definitely downgrade your iPhone back to iOS 4.3.3 from iOS 5; I’ve done it, and I can confirm it works. The nice thing is that not only does this tutorial help you downgrade, you also jailbreak your iPhone, killing two birds with one stone. Check out the full tutorial after the break…
Step 1: Place your iPhone running iOS 5 into DFU mode. You can watch the following video to learn how to do so if you’re not sure.

Step 2: Restore your iPhone to iOS 4.3.3 (Apple is still signing this firmware as of this writing of course, because it is the latest firmware). iTunes (10.3) should automatically recognize that your device is in DFU Mode, and will bring up the options to restore.

Click OK

Click Restore

Click Restore and Update

You can click restore and update in this instance, because iOS 4.3.3 is the latest publicly available firmware. Note: This will of course change if Apple releases an iOS 4.3.4+ so keep that in mind. In that case, you do not want to update, especially if there is no available jailbreak. If you’ve already previously downloaded iOS 4.3.3, it should start extracting the software and restoring your iPhone with no problem.
Step 3: Once you get near the very end of the restore, you will likely receive an iTunes error (1) recovery loop dialogue error. This can be disheartening to receive this over and over. Don’t fret though, we have a fix, and it’s called RedSn0w.
Step 4: Download the latest version of RedSn0w [Mac] from the Dev Team’s Blog, and extract the contents on your desktop. Now simply use the following video tutorial to run RedSn0w on your device. It’s a good idea to go ahead and put your iPhone back into DFU mode before proceeding.

Step 5: The only problem I encountered with running RedSn0w is that it froze up on the “Installing Activation Bundles” screen. If you wait more than five minutes, and it’s still frozen, simply follow this tutorial to fix it using TinyUmbrella to exit the recovery loop.

So folks, that’s it! That’s how you downgrade iOS 5 back to iOS 4.3.3. I hope that this tutorial was helpful for you and that it was easy to follow along.
Let me know if you have any tips or suggestions and report back in the comments section.

iOS 4.3.3 has just released to fix tracking issue founded recently on iOS devices. iOS 4.3.3 is available for download for iPhone 4, iPhone 3GS, iPod touch 4G, iPod touch 3G, iPad 1 and iPad 2.
