[Steps to Jailbreak your iPhone 3G[s] running 3.1.2 firmware]
-These steps will work just the same on iPhone 3G and also the iPod touch- Just make sure you download the right custom firmware.
These steps are really the easiest way to Jailbreak your iPhone or iPod Touch
*If you use the wrong firmware you will get a iTunes error Ex. if you use a 3G firmware instead of a 3Gs firmware*
*If your iPhone or Touch is not already jailbroken and you try to use a custom firmware, you might get the 16xx errors, so you will need a MAC at that point to do the last process or use blackra1n if you have a ligit sim because blackra1n will update your baseband, but with iPod touch it doesn't matter**I Am not a FAN of blackra1n** lol

Tools need to complete Jailbreak
1.iPhone 3Gs
2.Custom Firmware (iPhone2,1_3.1.2_7D11_Custom_Restore_Non Activated.ipsw) AT&T Subscribers
. (iPhone2,1_3.1.2_7D11_Custom_Restore.ips w) Non AT&T Subscribers Ex. T-Mobile etc.
3. iTunes 9.0.1
4. Firefox Browser [Other browsers have trouble downloading firmwares]

{Phase 1}
*Go to http://www.iphonefix.de/2009.2/?id=do...
*Click on [Connect to iPhonefix FTP HighSpeed] under FTP Access.
*Click on Firmware Custom System
*Download your custom Firmware [Best if saved on your desktop]

{Phase 2}
*Open Itunes 9.0.1
*Connect your iPhone 3Gs via USB and Itunes will detect it
*Press and hold Shift[PC] or Option[MAC] and click RESTORE
*Go to your desktop and click on the custom firmware
*iTunes will backup your device and then start the restore process
*After restore is complete if you with AT&T Itunes will activate your phone - Non AT&T will already be activated
*iTunes will now ask if you want to restore from back up or setup has new phone (Your Choice)
*After iTunes completely set up your iPhone you will have Cydia/Icy on your phone
*Jailbreak Complete.

{Unlock Process}
[IMPORTANT]- If you update your iPhone to 3.1.2 via itunes without a custom firmware or use blackra1n your baseband will be updated to the newest updated baseband 05.11.07 and you won't be able to Unlock your iphone until someone creates a baseband program to downgrade your baseband.

*To Unlock your iPhone turn off 3G under networks and then go into Cydia and do all the changes, Cydia will close - Go back into Cydia
*Click on MANAGE - Click Sources - Click repo666.ultrasn0w.com and do install
*After you install Ultrasn0w turn off your iPhone completely & Reboot
*Turn your phone back on, don't login just yet -Disable your sim password from your carrier phone *Remove the AT&T Sim and insert your carrier sim and wait for the iPhone to detect the sim and there you go [Unlock also]
**Remember do not turn on 3G*

Lata Zeen!

What you need to do is, when you jailbreak with blackra1n, use a custom firmware to overwrite the blackra1n jailbreak and you should be good or use the new dev team redsnow jailbreak for the 3.1.2 jailbreak
