redsn0w 0.9 Beta 3 Released!


Great news for the iPhone community!
Earlier today MuscleNerd annouced the realese of redsn0w 0.9Beta3. As you may know, redsn0w is a cross-platform jailbreaking, unlocking, and customizing tool for iPhones and iPod Touch which now supports FW3.1.2. (Keep in mind that this release is still BETA and you may come across some bugs)

redsn0w 0.9beta3

What is it?

A cross-platform jailbreaking, unlocking, and customizing tool for iPhones and iPod touches. Customizations include boot logos, recovery logos, and “verbose” boot. It’s a standalone program that doesn’t use iTunes (no custom IPSWs are involved).

The download links are at the bottom of this page (but please read the whole page anyway!).

We’ve been offering redsn0w in various incarnations over the years (including poorlad’s Windows version of QuickPwn). The most recent release before this one was redsn0w 0.8, which targeted Apple firmware 3.0/3.0.1.

What devices, platforms, and FW versions are supported?

The beta supports:

All iPhones and iPod touches except the iPod touch 3G
Windows and Mac OSX (x86)
Apple firmware 3.0 and 3.1.2
When it’s out of beta, it will support the iPod touch 3G, PPC OSX, and Linux.

If you need a carrier unlock, redsn0w will handle iPhone 2G by itself (by installing our BootNeuter utility). For the 3G and 3GS, use Cydia after you’re jailbroken to install ultrasn0w (baseband 04.26, preferred) or blacksn0w (baseband 05.11).

How is it different from PwnageTool?

redsn0w doesn’t require a system restore like PwnageTool does (it doesn’t even use iTunes at all). On the other hand, PwnageTool can prevent your baseband from being upgraded when you upgrade your firmware, preserving your unlock. (redsn0w doesn’t touch your baseband but it doesn’t help preserve it during an upgrade either).

redsn0w works by modifying your current filesystem, so your existing baseband, data and applications should remain intact.

How is it different from blackra1n?

It differs from blackra1n because:

It uses our original Pwnage bootrom exploit for iPhone 2G, iPhone 3G, and iPod 1G. (Because it’s a bootrom exploit, it can’t be fixed by Apple without a new hardware release.) Note that redsn0w 0.9 does use the USB exploit for iPhone 3GS and iPod 2G running 3.1.2, but that exploit will be fixed in Apple’s next FW release.
It offers custom logos and verbose boot
It installs Cydia without needing a separate download
It’s not as fast 🙂 (but redsn0w handles more variations :))
What if I have a late-model device?

If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC”, you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. That means you need to connect your device to a computer to complete the boot after a reset. Also, these devices cannot have custom logos.

redsn0w will ask you whether or not you fit in this category when used with the iPhone 3GS or iPod touch 2G. If you have a late-model device and don’t give redsn0w the correct answer, you will likely need to do a system restore to recover from the mistake.

To do a tethered boot after your late-model device resets for some reason, either run redsn0w again and select “Just boot tethered right now”, or run blackra1n.

What if I’m already jailbroken?

If you’re already jailbroken (by whatever means), redsn0w can still be used to change your boot logos, revert back to the stock logos, or switch verbose booting on and off. By selecting “Already Pwned” you can bypass the steps normally needed to enter the jailbroken state.

How long should it take

You should see a picture of a drive (“Downloading Jailbreak Data”) within 30 seconds of launching the jailbreak (after you’ve made your custom selections). It should then reboot and you should see a running pwnapple while the process is underway. It should finish within a minute or two after that, and will reboot on its own.

Is it safe?

The Windows version has been tested by small groups of volunteers on IRC and our blog since mid-January. That being said, this is still a beta and if things go wrong you may have to do a system restore…so make sure your data and pictures are synced before trying the beta.

Beta feedback

redsn0w is in beta until we get iPod Touch 3G, PPC OSX, and Linux support added. In the meantime, please send any feedback to MuscleNerd (either gmail or, or tweet with a #redsn0w tag. Please detail your device, OS, and any problem you find.

    I am about to try it out, and making a video of the process. Will report back…

  • 07ahamed

    Tried it on my iphone 3gs firmware 3.1.2 and does not work- i successfully put my iphone into recovery mode and started the jailbreak but i get a black screen. redsnow tells that the jailbreak is complete but nothing happens on my phone

  • Dusty

    Sounds good! Hope it works out for ya.

  • Cool. Let us know how this early beta goes!

  • wongnog

    Anyone know when an untethered jailbreak might come out for new model iPhone 3gs?I got mine for Xmas and was sad to learn all current jailbreaks are tethered for me.

  • rorypiper

    Not working in 3GS. Had same experience as 07ahamed. Worked great on my 3G.

  • Dusty

    Crappy. Well thanks for testing and well see when a new BETA or a final release is out.

  • Dusty

    I doubt for a while… well who knows. Hopefully someone is working on a untethered JB!
    I have no problems though with my 3GS and new iBoot. I recently had to replace my old iPhone 3GS as it crapped out and now have a new iPhone 3GS with new iBoot and so far its good! I never turn it off or need to restart, so really its a not a problem. Until one day its gonna crap out on me and ill have no computer with iTunes around to use blackra1n LOL Then ill be pissed!!! 😛

  • TeenWolf

    What's considered a late model? And does this jailbreak come with the same push notification problems?

  • Dusty

    Late model as in iPhone 3GS? I say after week 40. There was some older iBoot in week 42.

  • Michael

    i'm confused. Apparently this was tested on all phones INCLUDING the 3GS… I'm having the same problem on my pre-tether 3gs that others are reporting: redsn0w does its thing but phone never reboots – no pwnapple, and just hangs on a blank screen… Are we doing something wrong or is there a glitch for 3gs users that went unnoticed? Pls advise… Also, will ultrasn0w now unlock baseband 05.11.07?

  • Chris

    I thought the same, my 3GS had the new bootrom, no problems whatsoever until ONE time it rebooted on me while trying to get ahold of people out and about. Pissed doesn't even begin the describe it lol. Luckily that phone got replaced under warranty (cracks all over) and the replacement had the older bootrom 😀

  • Dusty

    Lucky dude with ur replacement having the older Bootrom! 🙂

  • rorypiper

    They have updated the Mac version, and I can confirm that this does work on the 3GS now!

  • rorypiper

    Mac version has been updated. Works on 3GS now. Download from same place as yesterday.

  • gwyn

    mine's the new 3gs. got black screen on the iphone even tho redsn0w ran through all the steps as expected. iphone didnt restart after redsn0w was done, just stayed at the black screen. had to press power button to switch off and on, but cydia wasn't installed.
