  • How to Jailbreak iPhone 3GS on 3.0 [redsn0w/OS X]
    This guide will teach you how to jailbreak the iPhone 3GS running iPhone firmware 3.0 on using redsn0w and OS X. This is NOT for firmware 3.1. After following this guide you can unlock your iPhone 3GS using ultrasn0w.

    Your iPhone 3GS should already be on firmware 3.0 before you begin.
    Download redsn0w 0.8 (OS X)
    Download iPhone 3GS firmware 3.0

    Extract the redsnow 0.8 archive. Run redsn0w. Click Browse.

    Browse to where you download the iPhone 3GS 3.0 firmware .ipsw. Select it and click Open.

    After a few seconds redsn0w will tell you that your IPSW has been successfully identified. Click next.

    redsn0w does some patching.

    Choose your options. Click next.

    Follow the directions to connect in recovery mode.

    redsn0w now uploads the needed files to your iPhone 3GS.

    After redsn0w is done uploading the needed files it says Done. You may click finish now. Beware your iPhone will be running the jailbreak at this time. Do not mess with it while it is working. Once it is done it will boot to the lockscreen and you will be jailbroken!

      Not sure if this was already answered, but do I have to restore my phone before jailbreaking so I will lose everything on my phone?

      Add me to the list of folks who seem to have successfully completed the steps only to find no Cydia. Tried it with both Icy & Cydia checked, and just Cydia - no luck either way.

      Wasn't working on my 3gs using redsn0w, says it finished but no Cydia. Then I tried it using the last Mirror link (mediafire) on the download page of redsn0w and it worked. Hope that helps anyone having the same problem

      Can someone remind me out to jailbreak 3.0.1 using redsn0w?? I know I need to point it to the 3.0 firmware but was that it? Just running redsn0w 0.8 (using 3.0fw) will jailbreak me for 3.0.1? I can't remember exactly.... All help is appreciated!!

      Does this still work even though Apple doesn't sign the old firmware?
