The iPhone Dev Team came through with their 2008 release date. Although the software is still in beta. There are a few features that are missing, but nothing real important. They will continue to work on the software to make it perfect.

STEP 1: Update to firmware 2.2 in iTunes if you have not done so already. Make sure you have the 02.28.00 baseband by visiting Settings – General – About

STEP 2: Launch QuickPwn and follow the onscreen directions to jailbreak/Activate your 2.2 iPhone 3G.

STEP 3: Open up Cydia and download all of the important updates.

STEP 4: Restart Cydia and click Manage at the bottom.

STEP 5: Click on Sources. Then hit Edit at the top left. Click Add. Then enter and press Add source. Once it says Return to Cydia, press that and then hit done at the top right.

STEP 6: Click Search at the bottom and search for Yellowsn0w. Click on yellowsn0w and install it.

STEP 7: Press the home button after it has installed to return to your main screen. Insert your new simcard.

STEP 8: Open up Settings – General – Network and set Enable 3g and Data Roaming to OFF.

STEP 9: Go Back to Settings – General – Reset and click Reset Network Settings. Your Phone will reboot.

STEP 10: Once your phone has booted up, wait 10 seconds for a signal. If you do not get a signal, eject and reinsert your sim and wait 10 more seconds. You should have a signal then. If you do not go to Settings and turn Airplane Mode on then off and you should have a signal.

-please note that if you reboot your phone and you do not have signal, flip the Airplane Mode on and off.

    If you are having problems try this:
    Restore iPhone with Stock 2.2.
    Jailbreak with QuickPwn.
    Turn on Caller ID.
    Turn off Data Roaming + 3G.
    Install Mobile Terminal with Cydia.
    Install yellowsn0w.
    Reboot iPhone.
    Insert SIM.
    Run Terminal.
    type yellowsn0w -r.
    wait 10 seconds.
    type yellowsn0w -c.
    wait 10 seconds.
    type yellowsn0w -r.
    type yellowsn0w -a (if busy message appears in under 15 seconds and No Service does not appear repeat this step).
    wait for it to load No Service and return back to 5 dots, wait 10 seconds then toggle Airplane Mode On and Off and it will work.
    If you remove SIM or reboot the iPhone all you have to do is toggle Airplane Mode to get it to work.

    So from what I gather this is still a pretty rough cut release? What happened to when the dev team said they wouldn’t release software til it was done, seems like the forced themselves in a corner with the whole New Years Eve thing.

  • Alan Vazquez

    Yeah. I think that the original yellowsn0w was done, but they had luck with 02.28.00 and had to redo the application. I expect there to be a solid 1.0 release by the end of this month.

  • kmi

    I have 3G 2.2.1(5H11) modem2.30. I try with Quickpwn everything I did, but unsucessful. When I put the sim it says invalid sim. Do you have any solution for it? Thanks.

    Folks by the way, if you guys tired or done with this junk software. I have suggestion for you guys, get “REBEL SIM CARD”. It works fine like original sim from AT&T. Don’t have to do nothing, just sim put it in. If you like to use T-Mobile. Try it you will love it.

    and trying to load Cydia with WIFI internet and it wont get it.
