UPDATE: IF YOU ARE TRYING TO UPDATE TO IOS 5 AND ARE GETTING ALL KINDS OF ERRORS LISTEN UP! UPDATE TO THE LATEST VERSION OF ITUNES. YOU -WILL NOT- BE ABLE TO UPDATE TO IOS 5 ON PREVIOUS VERSIONS.
IF YOU ARE UPDATING TO A PRE-DOWNLOADED IOS 5 (DOWNLOADED YOURSELF OUTSIDE OF ITUNES) THEN YOU NEED TO SHIFT+RESTORE -- NOT SHIFT+UPDATE. (OPTION+RESTORE ON MAC)
IOS 5 JAILBREAK IS NOW UNTETHERED!! (TETHERED MEANS THAT EVERYTIME YOUR PHONE TURNS OFF OR BATTERY DIES YOU WILL HAVE TO CONNECT TO A COMPUTER AND BOOT TETHERED WITH REDSNOW). SO, YOU CAN GO AHEAD AND UPGRADE THEN JAILBREAK IF YOU DO NOT DEPEND ON A CARRIER UNLOCK, OTHERWISE STAY AWAY AS IOS 5 CANNOT BE UNLOCKED YET.
This will Fix Error 1604 & 1605 on Your iPhone 3GS or 3G on iOS 4.0 !!!
If iTunes keeps giving you a 16xx error when you try to restore to iOS 4.0 custom firmware, follow these steps for a Jailbroken & Unlocked iOS 4.0 with on your 3GS or 3G. Confirmed working on my phone, 3GS accidently upgraded to stock iOS 4.0 and 5.13.04. Now running unlocked and jailbroken iOS 4.0 with Cydia and T-Mobile.
If using a Mac, press the Option button instead of Shift for Steps 2 & 6.
1. Change to sauriks serrvers (watch video)
2. Shift + Restore to factory 3.1.2 (link below)
3. You will get 1015 Error
4. Run Blackra1n (link below)
5. Take sauriks servers out of the hosts file (watch video)
6. Shift + Restore to iOS 4.0 Custom Firmware (link below)
If you simply want to get out of 1015 error after restoring, run blackra1n iReb.

WinRar:

To use these files you must download all parts of the Custom IPSW file that you want to use. Then use WinRAR to extract them. Just right click on ANY of the RAR files that you download and WinRAR will extract the files leaving you with ONE IPSW file that you will restore with. It doesn't matter if you extract Part 1, Part 2, Part 3, Part 4 etc etc, they will all extract the same way leaving you with just ONE IPSW file.

@ipartyboyy Windows Vista or Windows 7
Close iTunes and disconnect the iPhone, iPad, or iPod touch.
Click the Windows Start button Start button.
In the Start Search field type Services.
In the Programs section of the search results, Click "Services".
Select Apple Mobile Device and click Stop the service.
After the service has stopped, click Start the service.
After the Apple Mobile Device service has started again, open iTunes and connect the device.

Very interesting, got error 1600 BECAUSE of the extra line in the hosts file and deleting it helped. Must have been there from an earlier JB

@dersubtile Definitely, if you've used TinyUmberella at any point it would edit your host file.
