    Yes you can do this, but I don't think you should. Any firmware 3.1.3+ runs really bad on the iPhone 3G. If you still want to then follow the steps.

    1) Download sn0wbreeze from iH8sn0w.com | Jailbreak your iPod touches and iPhones

    2) Download a iOS 4.2.1 firmware for iPhone 3G: HERE

    3) Open sn0wbreeze and select the 4.2.1 firmware you downloaded

    4) Made sure you go on "Baseband Preservation Mode"

    5) Once you did that and it makes the firmware put your iPhone into DFU mode and restore it in iTunes with the custom 4.2.1 firmware you just made.

    ^ yep. I wouldn't go past 3.1.3 on an iPhone 3G. It is regarded by most as the best firmware for the iPhone 3G. You can shift+restore directly to 3.1.3 and still be unlockable. Although if you are on AT&T you have no need to install ultrasn0w, until you sell it and want to market it as unlocked.

    No you are going to shift + restore to 3.1.3. When in iTunes hold down the shift key and select restore. iTunes will let you browse to 3.1.3 firmware. Download 3.1.3 firmware from iPhone Download Blog

    Thanks a lot iPittsburgh, it seem to be a very simple and useful guide!

    Sorry for my ignorance but I have to be sure about some other things and hope you can answer to my questions!

    So, is there any problem that I am j/b and unlocked with Blackra1n and have Cydia & ********** on my iPhone?

    Can I do Backup on iTunes having those apps installed or I have to uninstall them before the Backup?

    The guy in the video says "you can restore from your backup on iTunes or unlock", so if I restore from iTunes am I going to get a unlock then ? If yes, any guide for that?
    I told you I'm a greenhorn, !!!

    Hope to get an answer for my stupid questions,!!!!!!!!!!
