For 1st gen iphones, iphone 3G, and 1st gen ipod touch users, this could possibly be a nice tool to have handy in times of need.

[EDIT2: iREB has been updated include an updated ShSh Grabber & integration of Sn0wbl0wer[/b][/u]
See the quoted iphoneclub article:
The new version of iREB of iH8sn0w is available for Windows. iREB provides a graphical interface for some features, including a different solution for 16xx and 21xx errors in iTunes when restoring a custom firmware (original iPhone and iPhone 3G) and iPod touch 1st and 2nd generation), a fix for the recovery mode Over (original iPhone, iPhone 3G and iPhone 3GS and all models of the iPod touch) and a ShSh grabber for iPhone OS 3.1.2 (3GS iPhone and iPod Touch 3rd generation).



With the new grabber ShSh 3GS users of the iPhone and iPod Touch 3rd generation functionality Umbrella use to ensure that they continue in the future jailbreaken. The ShSh data that are stored are needed at a later time to restore to iPhone OS 3.1.2, and firmware that Apple no longer signs.

It is important to keep in mind that you can never go downgrade the firmware then you have the data of ShSh. Saurik also to preserve its functionality it provides in Cydia, but with iREB can also ShSh data from an iPhone or iPod store (still) is not gejailbreakt. That you will use the ECID of your iPhone or iPod to enter. How can you find out that you can read on iSpazio.net. You can choose to ShSh data from Cydia or local store. We recommend it to both.



You can download iREB 3.1.2. More information can be found on the website iREB.
For questions you can also visit our forum.
Glossary:

* ECID: Exclusive Chip ID represents. This number is unique for every iPhone and iPod and the iPhone 3GS and 3rd generation iPod touch by Apple used to sign the firmware. The signature that you receive from Apple is only valid for your iPhone or iPod touch.
* ShSh data: ShSh-called blobs are the different files together for your iPhone or iPod from Apple personal signature forms. If that signature once you've stored on the server instance Saurik (the creator of Cydia), you can continue to use this signature to retrieve the signature of the firmware you have? even if Apple itself no longer signs this firmware. More information can be found in our article about Saurik? S Signature Server Firmware.

iH8sn0w has released a new update for iREB a new program for Windows and Mac that can solve the mistakes “16xx” and “21″ from iTunes that are displayed after a reset or a firmware downgrade.

The application is only compatible with EDGE iPhone, iPhone 3G and iPod Touch 1G and can be downloaded from here.

When you will be presented such an error will not have to do is start and follow the instructions on the screen. I recommend you download it and keep it somewhere in your computer .. It can come in useful!

From iH8sn0w official site:

Firmware 3.1 (7C144)/3.1.1(7C145) Supported
Devices Supported with iREB 2.2/3.1:


Downloads:
Windows or Mac

nice find sir mor.. just want to make sure i got this right,, so we are suppose to run this "If" we encounter an error,, or run this even before we restore so we will not encounter any error? thanks in advance!

I wrote on the 1st post that this is only a potential help due to me not being able to give it a test run. I think iREB stands for "iTunes Restore Error Bypass".

From my understanding of the instructions, you do indeed launch iREB if you encounter an the "16xx" and "21" errors after you attempt a restore. This tool will then guide you to working around the restore problem.

EDIT: instructions on how to use iREB from touchmania
To properly use the program you must do the following:
1. 3.1 IREB start.
2. iPod 1G, iPhone 2G or 3G to connect and bring to the DFU mode. Is (How can find out here)
3. Select the connected device in IREB.
4. After a few seconds, the screen of the device is first white and then red.
5. If the screen is red lets you click "Open iTunes to restore to a custom firmware open" to iTunes.
6. Once iTunes has turned up that was connected iPod or iPhone, you must select and hold down the Shift key, then click on restore and the custom firmware.

Annoying 16xx error recovery process, should now be a thing of the past.

iREB has been updated to include an iphone 3GS SHSH grabber.

Here's the surprise of iH8sn0w for users with iPhone 3GS: 3.1 ShSh Grabber
source: ispazio

Here are revealed the surprise of iH8sn0w for iPhone users 3GS. This is a new tool, integrated in the next version of iREB which will save the SHSH Firmware 3.1



This way you can downgrade from the future 3.2 In 3.1, despite the various blocks of Apple. However, there are already several options to save your certificate, especially one that offers saurik via Cydia, but it seems to iH8sn0w will preserve the possibility to perform the downgrade to both users and those with Jailbroken iPhone firmware original. Immediately following will give you the link for the download.

What can we do now if we have our ECID? Can we submit it to Saurik's server?

jay, I believe there's no other option as of this writing other than to wait for a tool to be released. Saurik only logs them if it is done via his Cydia grabber.

many times I've encountered this error during restoring cfw.
for me to solve this error, what I did is every iphone i will restore on cfw, i made them their own and it works.

Thank you Sir m.o.r for posting this fix for errors. i succesfully jailbreaked my iphone... Karma + for you. Thanks and more power to applei

* I had a chance to try this out yesterday and I can say that this is highly recommended if you dont have the OFW ipsw on hand. I just had to download the 5.5 mb iReb rather than download the 300mb+ ofw ipsw to prep device to pwned state before restoring to CFW.
