How to jailbreak iPhone 2G or 3G 3.0 firmware
First, let me start out by saying, BACK UP YOUR DATA. Do this both through iTunes and manually through SSH for your current jailbroken data. You never know when you’ll have to delete everything and start over. Also, this method is 100x easier than the Pwnage Tool. I recommend this for the average user.
If you need your phone UNLOCKED, this will not unlock it yet. This is only for ATT paying customers that activate through iTunes.
1. Search Google for iphone 3g 3.0 firmware or try these links
3.0.0 (2G): iPhone1,1_3.0_7A341_Restore.ipsw
3.0.0 (3G): iPhone1,2_3.0_7A341_Restore.ipsw
2. Download redSn0w for your OS and make sure it’s for the 3.0 firmware.
You can try here:

or google it.
3. Update your iPhone to 3.0. You can do this in iTunes by letting it do it automatically, or manually use the ipsw you downloaded. Either way is the same. Just make sure you are at 3.0 before you try redsn0w.
4. Run RedSn0w. This program has a wizard, but the general idea is: select the ipsw you downloaded, NEXT NEXT..etc. Then you enter your phone in DFU mode and redsn0w installs everything. It should be updated in a few minutes…you’ll see your iPhone showing progress.
5. Enjoy…you should have Cydia on your 3.0 firmward.
If all else fails, start over with restoring your iPhone through iTunes.
