  • Jailbreaking & Unlocking iOS 4 : What You Should Know
    Note: This Post will be udpated as news becomes available. Please share your experiences in this thread. It is highly suggested you do not update to iOS 4 right away. Please be patient.



    Today, as expected, Apple released iOS 4 to the public. But before you get too excited, there are some things you should know before updating to iOS 4. If you want to play Jailbreak with your iDevice, make sure you read through this.

    iOS 4 is compatible with the 3G, 3GS, the newest iPod Touch and iPhone 4. Those of you that have played with the GM release, the build number on this public release is exactly the same; 8A293. So as for changes since the GM there are none in this release.

    Update:

    Jailbreaking

    iPhone3GS & iPod3G owners (especially if you used Spirit for your first JB) should stay away from iOS4 for now

    Wizdaz has kept the community in the know, informing us that PwnageTool is currently being updated as we speak. PwnageTool 4.0 will support the iPhone 3G (with Pwnage exploit), iPhone 3GS and iPod Touch 2G (both with 24kPwn exploit). Keep in mind this means no support for the newer bootom. Remember the tethered days? If that was you, then you will need to wait until Spirit is updated or a new tool is updated for such.

    There is of course the Redsn0w option if you have a 3G, but stay away from any custom packages. The Dev-Team has written it well, and because of their credibility, here is exactly what they say

    We are working hard on a release to our tools that will jailbreak your device (or give you iOS 4 via the jailbreak train) and provide you with a carrier unlock.

    Until these tools are released you should hold off on updating your device until we have fully tested our tools with all the relevant devices.

    If you rely on hacktivation or a carrier unlock (ultrasn0w) then you should not upgrade until we have fully tested and released our tools.

    Don’t be tempted with unofficial PwnageTool/redsn0w bundles or releases, just check here or our team twitter for real time release information.

    Remember, we risk our devices so you don’t have to (but this time anyone who has made a mistake upgrading their baseband firmware at 3.1.3 or 4.0 should be OK real soon Now!

    Unlocking iOS 4

    The iPhone Dev Team has released ultrasn0w 0.93 for unlocking your new iOS 4. Simply add the Cydia repo: repo666.ultrasn0w.com. This version of ultrasn0w will unlock basebands 04.26.08 thru 05.13.04. If your unsure, that means that ultrasn0w unlocks ALL basebands since iPhone OS 3.1. Even more specifically, 04.26.08, 05.11.07, 05.15.01, and 05.13.04. Remember to disable 3G on T-Mobile USA.

    So on the unlocking front, you're pretty much golden. However it's still recommend to wait just a little bit longer before making the plunge for iOS 4.

      I've spent the last six hours trying to get iOS4 on my iPhone 3G, getting redsn0w to recognize the IPSW and finally the JB. When all is said and done, i got iOS4.0 (updated through itunes, then manually restored w/ downloaded IPSW) working and unlocked with T-Mobile.

      FYI:If anyone tries to update to iTunes 9.2 and then iOS 4, you can't do it if you have a cracked version of wifi sync. Also, once you let itunes 9.2 update your phone to iOS 4, then download the iOS4 IPSW (iPod, iPhone and iPad Firmware Download) to your desktop and put your iPhone into recovery mode. iTunes will tell you that its in recovery mode, click OK, then hold SHIFT and click on the RESTORE button. Find the iOS4.0 IPSW you downloaded and let iTunes restore it. Once its done, download the latest Redsn0w version (0.9.5b5-3, run it, go into cydia and add repo666.ultrasn0w.com/, install ultrasn0w and you're done!

      How are you guys making redsnow recognize IPSW4.0? Some who are updating to OS4 are still not getting it to work for some reason.

Please be patien and give me a simple explanation, I know I am very very foolish noob:-))
      You need to hacktivate your phone. The gold master version of Redsn0w didn't have this feature. I think it's been added now.

      My guess is you didn't read carefully enough and you have a 3gs phone and not a *3g* phone. It does not work for the 3GS yet.

      Yes, iBooks was working perfectly for me on my iPod touch 2g before the jailbreak, and after the jailbreak none of the books or PDFs will show up even though iTunes confirms they are syncing and on the device

      glad I'm not alone. I'm sure a fix is in the works...though really, I had no intention of reading books on my iPhone. lol
