hi
here is solution of Downgrade iPhone 3G & 3GS From iOS 4 To 3.1.2
i tested many times 3g or 3GS 100% worked.

1. Open the file C:\Windows\System32\driver\\etc\hosts (Windows) or /etc/hosts (Mac OS X) and add the following entry to the bottom of the file.
74.208.10.249 gs.apple.com

Restore
———-
2. Connect your iphone

to the USB and put it into DFU mode. iTunes will display an alert stating you need to restore your device, click ok then hold option + click restore and navigate to your previously downloaded 3.1.2 FW.

3. After the restore finishes you should be hit with a 1015 error. That’s expected. Your phone should be in Recovery mode now and itunes will tell you to restore again. Click OK then hold option + click on restore again – this time you do not have to go into DFU mode – and navigate to the 3.1.2 FW.

Jailbreak
———–
4. After the restore finishes again it’ll throw another 1015 error. That’s expected again. This time, just select OK and close iTunes. Fire up redsn0w – make sure it’s the 0.9.4 version – and jailbreak as normal. Uncheck all the ticks while jailbreaking.

5. After the jailbreak is finalized your device should reboot and strange enough you successfully downgraded to 3.1.2.

Update: If your iPhone goes in Recovery Mode loop, use RecBoot to get out of it. It is a brilliant [COLOR=#0000ff! important][COLOR=#0000ff! important]application[/COLOR][/COLOR]

which will get you out of continuous never-ending loop.

Thank you.
