  • 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.

    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!
    iPhone Dev-Team

    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.

      Why do we need to disable 3G service when unlocking

      Most people unlock to use their phone with TMobile, and TMobile's 3G band is not compatible with the iPhones.

      Nice!, Standing by for the certified jailbreak instructions. I'm in no rush. I'll have the new iPhone 4 on Thursday and my 3GS will become my spare/test/around the home idevice.

      you can already jailbreak 4.0, just use the same redsn0w 0.9.5 beta and have running the official 4.0 and when redsn0w asks you for the ipsw just enter the goldmaster 4.0, they both have the same build so it works...but only on ipod touch 2g and iphone 3g

      [SIZE="6"]hello guys

      today when the iPhone 4 unlock came out I opened cydia to add ultrasnow's new repo to unlock. After adding it said that cydia needs to be updated so I tap on essential updates. During installation it got stuck at springboarb reloading. I got confused and after waitin for a long time I manually rebooted iPhone. After that the Apple logo appeared and stayed on for about 5 mins and than phone came into normal form but now cydia just doesn't installs anything. Either I try to upgrade or install any new app or even cydia isntaller new update it just doesn't installs and after the process show that it's still not installed. What should I do? I need to get it working cuz I need to unlock

      If i have a brand new 3GS from apple today, would I be able to unlock it?

      How are people unlocking iOS 4.0 if there isnt even a jailbreak for it yet? This is whats confusing me.

      If someone could clear that up for me itd be greatly appreciated.

      Thanks guys.
      Because you can jailbreak an iPhone 3G and iPod Touch 2G which I believe then can be unlocked using apps in cydia, and you might be able to jailbreak, idk about unlock bc we have new bootroms in the new 3GS's, they changed them randomly during their sales. Though I'm sure the DevTeam is working with the new bootrom, as it should be assumed it could be used in iPhone 4.
