iPhone iOS 4.2: Jailbreak and Unlock – Redsn0w 0.9.6 Download Available

By Alan Ng - Sep 21, 2010

Earlier on we informed you that Redsn0w 0.9.6 was now available to download and jailbreak iPhone iOS 4.1, but now we can also confirm that the same tool works on the beta for iOS 4.2 too.

As reported from RedmondPie, the Redsn0w jailbreak tool isn’t available on the iPhone 4 or new iPod Touch yet, as iPhone Dev Team member MuscleNerd has confirmed via Twitter that the iPhone 3G and 2G iPod Touch are the only supported devices at the moment.

Unlike other jailbreak methods, this one doesn’t seem to be straight forward, so we only recommend trying this out if you have performed such tasks before. If you’re willing to give it a go, you will find a complete set of instructions over at RedmondPie here.

Can you confirm that the Redsn0w jailbreak 0.9.6 tool works for the iPhone iOS 4.2 beta? Leave us a message so other users can try it out.

  • I jail broke and unlocked my iphone 3GS with redsn0w_win_0.9.6b5 successfully. It is working great. The only drawback I have seen is the Battery time is gone for a toss. The charge is not remaining for more than 5 hours(Standby).

    Does anyone know how to fix this?

    guys IOS is not the issue on unlocking, its the BASEBAND!!
    to know your baseband go to SETTINGS/GENERAL/ABOUT and check the MODEM FIRMWARE = THATS YOUR BASEBAND!!
    whatever kind of iphone you have if it says 5.14/2.10/3.10 – FORGET IT!! JUST WAIT FOR THE DEV TEAM TO RELEASE THE NEW SOFTWARE!
    as for 3G/3GS with modem firmware 5.14 (I'VE DONE THIS PERSONALLY) upgrade your baseband with the ipad 6.15 baseband by using redsnow..and your good to go..
    i have 3G with 4.1/6.15 and running with simple mobile..

    You know what I truly give up this is why apple sucks an it’s gay. I tried giving apple a chance an i left the awesome android for this unlocking and jailbreaking bs!!! I have waited over a freaking month for this retarded 4.1 unlock. Nobody nowhere mentioned the fact if you have baseband 02.10.04 that you will be assed out and have to wait longer. During my everlasting wait my tmobile service was cutt off an now I have to pay more than ever cuz I really was banking on this unlock.

    Ultrasn0w is an unlocked tool that you need to install after jailbreaking your iPhone. Limera1n, greenpois0n, redsn0w and sn0wbreeze are just jailbreaking tools and have nothing to do with unlocking your phone. If you owned a 3G or 3Gs with a baseband of 5.13 or lower, and iphone 4 with a baseband 1.59 you can unlock your phone right now. For those with baseband 5.14, the new ultrasn0w 1.1-2 will be released this Sunday. IPhone 4 with a baseband 2.10 will have to wait as the unlocked tool is not available. If you upgraded your iPhone to 4.2 through iTunes , then your phone will turn into an iPod, unless AT&T is your carrier

    Heres a thought….dont install Betas in the first place! Sure fire way to brick your device. Let Devs make stable JBs for christ sake
