DEV-TEAM had released redsn0w 0.95 beta 3, which is able to jailbreak iOS4 on iPhone 3G (not iPhone 2G, not iPhone 3GS).

Files that required when doing jailbreak and unlock:
1) iPhone 3G iOS4 firmware, download as below:

iOS 4 GM seed – iPhone 3G, 292.3MB

2) Redsn0w 0.9.5 beta 5-3, download as below:

Jailbreak Steps:
0) BACKUP your DATA on iPhone before proceed further!
1) Restore(in iTunes, press shift+Restore button, look for the iOS4 ipsw files, and click OK) your iPhone 3G to iOS4.
2) Run “redsn0w.exe”, which extracted from the downloaded redsn0w zip file.
3) Select the iOS4 ipsw file, which you used to restore you iPhone 3G just now.
4) Select the options that you would like to enable in the Redsn0w Jailbreak process.

5) Connect your iPhone 3G to the USB cable, which connected to your PC, switch off your iPhone 3G (press top power button until “slide to power off” message appeared, then slide to power off.). Click NEXT after you done these.
6) Follow instruction on screen:
- Hold down top power button of your iPhone 3G, DON’T release!
- Without releasing power button, hold down Home button for 10 sec (now you know why I ask you not to release the power button).
- Without release Home button, release power button. Keep holding Home button until your iPhone 3G get into the running pineapple screen.
7) Once finished, reboot your iPhone 3G. Your iPhone 3G should now been jailbreaked.

    DO NOT enable multitask & homescreen wallpaper.
    3G @ iOS4 is uber lag. I’d jailbroken for 3 of my friends & they wanted rather revert it back to 3.1.3 or disable multitask & wallpaper.
    It’s advised to stay @ 3.1.3 for performance as of now until Apple fixed the issue.
    2 cents.

    kpd Desmond : Sesetengah model iphone 3G (MC model) tak boleh nak jailbreak menggunakan redsn0w..Cuba gunakan greenp0is0n 6.1 utk jailbreak ke 4.2.1 dgn Network Unlock…
    Maaf jika tidak membantu..Selamat Mencuba…
