  • 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.

      Guys IDK what saurik did but DO NOT download the updates from cydia. For whatever reason they put you into an infinite Reload Springboard loop. If you then restart it manually it goes into apple logo for 5 minutes then returns back to normal but cydia is more or less disabled. you can still browse but downloads DO NOT work. Rock However still does. yeah he f****** something up. Not sure if its only 3GS's or what but DONT download until it is fixed

      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
      Same thing happened to me today. I updated cydia, then resprung, went back into cydia and updated the mobilesubstrate and then it went to go and respring, after about 5 mins it was at the spinning wheel so I had to manually do a reset after phone booted up it was on apple screen for a few minutes then the phone started normally. I went back to cydia to check and see if everyone thing was ok but cydia returned a bunch of errors. All I know is that something screwed up when I updated mobilesubstrate.

      I don't want to have to re-jailbreak my phone, I have too much to download again from cydia if I do. I might as well just wait for the 4.0 jailbreak.

      read this Jailbreak iOS 4.0 iPhone 3G, iPod touch 2G with Redsn0w 0.9.5b5-3 [How to Guide] | Redmond Pie

      there ARE differences between the GM and the OFFICIAL 4.0. redsn0w 0.9.5b-3 will jb the OFFICIAL 4.0 fw. IF you are on the OFFICIAL 4.0 0.9.5b-2 will not jb the GM version! just tried, found the beta3 and it works w/ the official fw.

      It works for me just fine:

      iPhone 3G has been updated to 4.0 software via iTunes 9.2
      .ipsw file of version 4 has been copied from iTunes iPhone Firmware folder
      redsn0w .095b5-3 (windows) has been downloaded
      it perfectly recognized the .ipsw which I got from iTunes folder

      Jailbreak process took 3-5 minutes. Now I have Cydia on 4.0 software.

      Goodluck to everyone who is in process...

Cydia however is more or less inert and will NOT install anything. it gives a POSIX connection refused. this is on wifi and 3G service... Im testing Rock right now. Oh and my theory for why it is messing it up is that he updated so many essential tweaks at once that they have some combined side effect on cydia.

      Rock is confirmed to work. It can still have full functionality. GO ROCK
      So is there anyway to fix this other than re-jailbreaking?

      It's always good to have iFile and ssh installed with these jb phones.In that cydia case,I beleive in the updates/dpkg folder you delete the files in there and cydia starts to work again.Also,before bashing saurik or any other dev out there that has dedicated their time and effort without charging you a penny to use their programs,tweet them or try to contact them before posting stuff like that.

      I just received a refurbished iPhone 3gs 3.1.3 on baseband 05.12.01 yesterday. I jailbroke it with Spirit. I wanted to do a clean restore to 3.1.3 then re-jailbreak the phone but I couldn't restore through iTunes (kept getting error 1600 and 1604 in recovery and DFU mode). So I tried erasing the phone through settings. After everything was erased the phone got stuck on the Apple Screen with the little wheel thing. I tried putting it back into recovery mode and DFU mode and restoring custom 3.1.3 ipsws but I still get errors 1600 and 1604. Is there any way for me to go back to 3.1.3?

      I updated all the essential upgrades and I'm able to install packages and everything like normal on my 3GS.

      Has anyone tested the cydia updates on a 3gs on 3.1.2? Is it making the infinite re-spring loop?
