  • iPhone OS 4.0 Jailbreak is Released


    One week from the day Apple announced OS 4.0, the iPhone Dev Team releases a jailbreak. This jailbreak is for developers to get ahead start on updating their apps for 4.0.

    Details from: redsn0w 0.9.5 BETA [iPhone Dev Team]

    This is a beta release of redsn0w targeted at developers of jailbroken apps.

    Please not that this beta is not meant for the average end-user. There are many things “broken” with jailbroken apps in the 4.0beta1 environment right now, and this beta redsn0w allows the developers behind those jailbroken apps to fix their software before the general public gets iphoneOS 4.0.

    Because it's meant for JB app developers, this beta redsn0w does not perform hactivation. You'll need a properly-registered developer UDID with Apple to get past the activation screen. For similar reasons, there is no Windows version of this beta redsn0w (since apps are developed on MacOSX). Please don't pirate Apple software.

    Anyone other than developers of jailbroken apps porting their software to 4.0beta1 should still be using our previously-released redsn0ws for 3.0 through 3.1.3
    This BETA release supports:
    • iPhone 3G only (for now)
    • Mac OSX only (for now)
    • the 4.0beta1 FW only (for now)

    YOU SHOULD STAY CLEAR OF THIS BETA SOFTWARE IF YOU RELY ON A CARRIER UNLOCK. That's because the beta redsn0w works only if your device has already been upgraded to the stock 4.0beta IPSW from Apple, which contains a baseband update. If you installed that IPSW, you've already lost the carrier unlock until the next planned release of ultrasn0w and blacksn0w.

    YOU SHOULD STAY CLEAR OF THIS BETA SOFTWARE IF YOU RELY ON A CARRIER UNLOCK!

    Enjoy!



    EDIT:

    Multitasking on your 3G

    Once you are jailbroken, navigate to /System/Library/CoreService/SpringBoard.app/N82AP.plist

    Open the plist and change the multitasking key to = True

    if the multitasking key is not there, add it

      Why did you buy an iPhone you can't use? Shouldn't you have just bought the HD2 in the first place if that's what you can use on your carrier?

      I got mixed up with the jailbreak rules regarding firmware updates and locked myself out of the phone

      Hi guys I have been given an iPhone from states side, that is Unlocked and not sure if it has ever been jailbroken before.

      It's an iPhone 3GS
      Version 4.0(8A293)
      Model MB718LL
      Modem Firmware 05.13.04

      My question is can this be Jailbroken? As for SH Blobs, as mentioned earlier am not sure if it has ever been jailbroken before, or SH Blobs saved elsewhere. For now lets assume never.

      Kindly advise if the Snowbreeze 1.6 method mentioned at he start can work on this, or which other method would work.

      Cheers.

      You should be OK with the 4 soon - then you can get rid of the HD2 - if you want too.

      It depends on what jailbreak method was used before. You need to downgrade it back to 3.1.2 and jailbreak with blackrain again. Look for a thread to downgrade it. I did mine and its working fine.

      You need to jailbreak again. Can you post model# and firmware on your next message.

      If you didn't save your SHSH for 3.12 you can not JB 4
      If you saved your SHSH for 3.13 only you can downgrade to 3.13 and use Spirit then UltraSn0w.
      If you don't have any SHSH you are SOL
      Foe now.

      It makes absolutely no difference without having the SHSH saved.

      Yes, and with a 3GS you can't do that without your SHSH

      The model number has nothing to do with it, but like I said, you can not restore a 3GS that is on 4.0 with 3.xx unless you have your SHSH saved.

      Can i just keep 4.0 update on for now and then jaibreak when the 4.0 jailbreak is released or will i have to downgrade frist to jailbreak 4.0. I did not jailbreak phone the frist time i took it to radio shack and they jailbroke it for me. This time i want to do it myself. But when i downloaded 4.0 i did back up my 3.12 software. I need step by step instructions.

      Stay where you are and wait. Make sure you have your 4.0 blobs saved:
      iphone_dev twitter

      3GS, ipt3G, iPhone4 users (regardless of current FW or JB status) should backup 4..0 SHSH blobs The Firmware Umbrella
