Now iPhone Dev team has confirmed that they will not be releasing any jailbreaks for iPhone OS v4.0.2. Now this is a bad news for all the people who have accidentally upgraded their OS version to 4.0.2.

But there is way by which we can downgrade our OS version to the previous version. ie., 4.0.1 for which jailbreak is still available.

This step by step guide will show you how to downgrade your iPhone

iOS 4.0.2 to iOS 4.0.1. These steps are pretty simple but there is one major requirement: you must have your SHSH files saved on Saurik’s server. There is absolutely no way around it. If you don’t have your SHSH, you won’t be able to downgrade your iPhone.

In this tutorial, we will see how to downgrade the iPhone from 4.0.2 to 4.0.1 but the steps are the same if you want to downgrade to iOS 4 or even 3.1.3.

There are several methods used to downgrade the iPhone. We will learn the method that uses TinyUmbrella. No file editing will be necessary.

How to Downgrade from iOS 4.0.2 to 4.0.1

Step 1: Let’s download your SHSH blobs from Saurik’s server to your computer. To do so, download TinyUmbrella and plug your iPhone in. Select the “Advanced Options” box. Also select the firmware version to which you wish to downgrade. Finally, select “Cydia” under “Request From”. Then hit “Save My SHSH”. This will grab your SHSH files from Saurik’s servers and save them on your computer.

Step 2: Download the firmware to which you wish to downgrade to from our iPhone downloads section. Save it to your desktop.

Step 3: Put your iPhone in DFU Mode. To do so, launch iTunes and plug your iPhone in. Press and hold the Home and Power button together for 10 seconds. After 10 seconds, release the Power button while still holding the Home button until iTunes pops up and says it has found an iPhone in recovery Mode.

Step 4: Run TinyUmbrellaand click the “Display SHSHs” button to make sure your SHSH blobs were downloaded to your computer. Once done, click “Start TSS Server”.

Step 5: Now we’re going to restore to the firmware you want. To do so, launch iTunes and plug your iPhone in. Hold to SHIFT key (Windows only) or ALT/Option key (Mac only) while clicking on Restore. Make sure you hold the key while clicking Restore. A window will open. Simply select the firmware you downloaded in step 2.

Step 6: Your iPhone will start the restore process. You will most likely get several errors (error 1011, 1013, and 1015) but that’s ok, don’t worry about those.

Step 7: Finally, we need to get your iPhone out of recovery mode. To do so, simply click “Kick Device Out of Recovery” in TinyUmbrella.

Done!

A lot of people have been reporting issues with jailbreaking using the new blackra1n tool by George, specially iPod Touch 3G owners. Some of these issues have to do with the fact that this is a tethered jailbreak for iPod Touch 3G so far. This means that to boot your iPod Touch 3G, it must be plugged into your computer and you must run blackra1n again. For those stuck at a white screen or being unable to boot your device, here are a few important pointers to keep in mind during the process:

• Make sure you’ve updated to 3.1.2. This jailbreak is not for 3.0 or 3.1.
• Download the purplera1n tool to your desktop. Some users have reported issues of the application crashing or having issues with rights on Vista or 7. This should fix those issues. For more convenience. run it as an administrator.
• Make sure no other software is running when you jailbreak to avoid interference.
• If your device doesn’t boot for a long time, hold down the power and home buttons and restart it. If it tells you to connect to iTunes, something must have gone wrong and you might have to restart the process. I know this is annoying, but it has worked for some people after some tries. It does work.
• You won’t lose your data by jailbreaking. Only a fresh firmware restore could mean that your apps might go away, but they can be synced back using iTunes.
• If you have a white screen turn off the device by holding the power and home buttons for 10 seconds and boot it again.
• If iTunes keeps popping up, use CTRL + ALT + DELETE to go to the task manager and kill all iTunes processes which includes iTunesHelper.exe. This can cause interference with the process too.
• Strangely, doing the process on different computers has also worked for some people.

In the end, keep in mind that blackra1n really works. I tried it on my iPod Touch 2G 8GB, and it worked in the first try. It only got stuck when running Cydia for the first time. I had to reboot using the Power + Home buttons trick, but after that it has been really smooth.

Update: George Hotz has tweeted about an important issue that most people are facing. You’ll have to check if your iPod Touch 2G or 3G, 8GB model starts with MB or MC. For MC it won’t work, so you should restore it back to the old firmware. It works fine for the ones that start with MB. I guess that should answer most of the issues people are facing with blackra1n
