    Smile [Release: 3G] iPhone OS 4 Jailbreak redsn0w 0.9.5b2 [April 17]

    I don't think much people caught onto this yet, but a release for the 4.0 jailbreak has been released but for iPhone 3G Only!

    To do so:

    Download:
    - Latest iTunes 9.1
    - Redsn0w 0.9.5b2
    - iPhone OS 4 Beta 1 (Google is your friend)

    Pre-Install Steps:
    - Make sure that you have iPhone OS 4 Installed on your iPhone and that it has been activated by its UUID via developer account registration or others...
    - Make sure the latest iTunes is installed for best outcome
    - Make a note to self that this is usually intended for developers only
    - If not noted already MAC ONLY for now
    - Goodluck!

    You should mention that any unlockers should avoid using this as well sense there BB will be upgraded if they use the unlock but are also on a supported carrier
    Thanks to alpineflip


    DO THIS AT YOUR OWN RISK!


    1. Install all software listed above

    2. Run redsn0w 0.9.5

    3. Click "Browse"; locate your 4.0 beta 1 firmware --> click open

    4. Select 'Install Cydia'

    5. Make sure the iPhone is off and plugged into the computer.

    6. Put your iPhone into recovery mode

    "Connect your device in recovery mode by pressing the Power and buttons continuously.

    At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
    " [Taken from Redmondpie]

    7. The installer will do the rest just make sure the iPhone is connected at all times and do not turn off your computer.

    8. When you boot back into your iPhone after jailbreak you will see a white icon that is 'Cydia'

    9. Launch it and navigate over to sources and add the source:


    10. Do a refresh

    11. Restart Cydia and you should be seeing the regular Cydia Logo







    Extras:

    How-to Enable Multitasking:

    Once done, you can now enable multitasking on iPhone 3G, OS 4 by simply editing a N82AP.plist file as mentioned here. Open the said .plist file and change the multitasking key to = TRUE. If the is not there, add it and you’ll be done.

    For iPhone 3.1.3 firmware, you can follow our complete jailbreaking guide for iPhone 2G, 3G, 3GS and iPod touch 1G/2G using redsn0w 0.9.3, redsn0w 0.9.4, sn0wbreeze, PwnageTool 3.1.5. Unlocking can be done using ultrasn0w or blacksn0w.

    For iPhone 3.1.2 firmware, you can use blackra1n, PwnageTool, redsn0w, sn0wbreeze, ultrasn0w and blacksn0w to jailbreak and unlock your iPhone and iPod touch.
    (Redmondpie)


    Alert! Make sure you know that you must have a developer account because you need to have your phones UUID activated and registered before upgrading to iPhone OS 4



    Post any changes to steps in forum thanks.
    Sincerly,
    John

    PS: I will update this thread when the 3GS jailbreak comes out.

    I doubt that there will be a jailbreak for 3GS during the iPhoneOS 4.0 betas. This would involve showing Apple the new exploit that the jailbreakers have. My speculation is that they will not do this before 4.0 is released

    The iPhone 2G is never going to receive OS 4.0. Apple has made that clear.

    The only way you will see OS 4.0 on a 2G is via the hacking community. It is potentially possible, but not easy. The 3G is quite similar to the 2G (same App CPU, but different Phone CPU and other slight differences. It might be possible to get the 3G 4.0 OS working on a 2G, biggest challenge would be getting the phone part of 2G working and making the 3G kernel work on a 2G iPhone

    Without source code for the kernel of the iPhone OS, it is quite a tricky task. I don't think anyone has really thought about attempting this.

    iPhone 2g cannot update to 4.0 so no.

    As for 3GS, dev team could release pwnage tool and allow those 3GS units with old bootrom to update to 4.0 but don't know if they will go to all that trouble for a beta.

    As I explained, this is a marketing decision, there is no technical reason why Apple will not offer OS4.0 on a 2G phone.

    For the 3GS, I doubt that they will go to such trouble for a beta. Releasing redsn0w beta for 4.0b1 was a new step for the devteam. It is purely so that jailbreak app developers are up to speed with OS 4.0 at release time.

    Redsn0w for 3GS running 4.0 won't happen before, requires revealing a new iBoot exploit to Apple. Such an exploit should not be wasted on a beta.

    Think is not possible to use same (or a variation) for 3.1.3 exploit, right?
