  • 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.

      Yes, redsn0w jailbreaks it - ultrasn0w unlocks it

      So getting an upgrade loop with ultrasn0w and want to know if anyone else is getting it. I install, phone reboots, go to Cydia and it says there is an upgrade from ultrasn0w again. If this isn't normal, anyone know how to fix it possibly? Thanks.

      Update #1: redsn0w beta has been updated to hacktivate iOS 4.0 for iPhone3G (in addition to jailbreaking the iPhone3G and iPod Touch 2G).

      For now, the redsn0w beta release supports only the iPhone3G and iPod Touch 2G at todayís 4.0. Itís still a beta, so youíll need to let Cydia reorganize, reload, and update after using redsn0w.

      Like always, and I know it might take a minute, but read all the posts and you should know what's okay, what's not okay, and how to do it all.

      Awesome job Dev Team!

      I tried jailbreaking with redsn0w 0.95b with the GM IPSW. It acts as it if jailbreaks it (pineapple screen, etc). But in the final reboot it just returns to the "Connect to iTunes" screen. Oh well. good think I'm not in a a hurry to sell my 3G...def need 4.0 to sell for more $

      Does ANYONE know a way to jailbreak an iPhone 3gs when it's on the emergency call screen, even if it's on 3.1.3??? I'm desperate.

      i sold my 3gs a few weeks ago so I cant test it but from what I read is that sbsettings is fine , you just need to go into activator in settings and set a function to sbsettings it self? Like swipe to left etc.

      let me know if that works.

      for those wondering what I did to jailbreak my 3G phone with ease, I followed this guide:

      How to Jailbreak iOS 4.0 PUBLIC RELEASE Firmware for iPhone & iPod Touch | AllTechRelated - Your #1 source for all the latest news, reviews and guides on the iPhone, iPad, iPod Touch and everything tech related.

      it was very simple. just make sure you grab the official firmware AND the iOS4 GOLD MASTER version from some days ago for your Phone. update your 3G phone to the official release from today, then jailbreak it with the iOS4 GOLD MASTER + RedSn0w .05 Beta 5-2 and you're good to go.

      NOTE: the instructions at the link are ONLY for the 3G. not 2G. not the 3GS. not the 4G.

      NOTE 2: also, when you update your 3G, it will erase your phone and install the new firmware, so backup first.

      NOTE 3: your phone has to be activated before iOS4 will install.

      From your post you have the wrong version of redsn0w. You need version redsn0w 0.95b5-2

      you're not supposed to use Redsn0w with the official firmware. you're supposed to use it with the GOLD MASTER release.

      you should update your phone with the official release, then jailbreak with the GOLD MASTER release.

      and this is all assuming you're using an iPhone 3G.
