Geohot exploit + Comex userland tools to keep Apple A4 iPhones Jailbroken and untethered Forever

iPhone Dev Team's MuscleNerd has announced via twitter that Comex's Userland Tools can be used to keep all Apple A4 chipset-based, Jailbroken iPhones, iPod touches, and iPads untethered for all future firmware releases. Coupled with Geohot's limera1n exploit which will work on all current A4 devices for the duration of their lifespan, and iPhone Dev Teams custom pwnagetool which will keep your baseband unlockable, Jailbreakers can look forward to being up to date with all current firmware releases without any worry of losing their Jailbreak or Unlock status.

  • Pwnagetool lets you create custom firmware with older baseband to preserve unlock (iPhone 4 owners can also use TinyUmbrella)
  • Comex Userland Tools are built into both limera1n and greenpois0n to keep Jailbreak untethered.
  • Geohot Exploit is a bootrom-level exploit that can't be closed without new hardware from Apple.

Geohot exploit + Comex userland tools to keep Apple A4 iPhones Jailbroken and untethered Forever


So does this mean you'd be able to jailbreak and then when future updates (such as 4.2) come put, you could update no problem?

Alex, this means that all future firmwares will be Jailbroken and the Jailbreak releases should come out much faster and smoother...

so if i jailbroke my ip4 with limera1n am i ok to stick with it or should i re-virginize my phone and jailbreak it with this now?

Not all jailbreaks are equal. However, if you don't have any problems with a jailbroken phone, and it's not tethered, there is no reason to redo it. I suppose I should point out that userland jailbreaks aren't the same as bootrom jailbreaks. That's the reason people that used Spirit to jailbreak couldn't upgrade with pwnagetool. But, limera1n and greenois0n are bootrom based, so as long as you aren't having problems, stick with what you've got.

Do i have to jailbreak my jailbroken 3.2.1 iPad again with limera1n in order to enjoy the forever jailbreaking?

There seems to be a bit of confusion... This is not a new JB. They have just refined their tools for use with FUTURE JB releases. It doesnt change anything for the current firmware and current JB. The process will always have to be repeated on future releases. This news just confirms that future firmware releases will be Jailbroken...

This is great news for 2 reasons.
1. I love jailbreaking.
2. Apple will have to use a better chip than the A4 sooner.

iPhone 4 on iOS 4.1 (witth 4.2 coming soon) i don't see any reason to jailbreak... i like my phone as it is...

Ok I'm new to JB so I have a question. So when 4.2 comes out, I have to upgrade to it and then re-jailbreak again with either Limera1n or GreenpoisOn?

2 questions.
1. If I jailbroke my iphone 4 on the day that limera1n was released, do I have to re-jailbreak it now? Is this something that was just added, or is this article just notifying everyone what limerain actually included?

  1. When Apple releases a new firmware. Will I have to re-jailbreak with limerain, or will the phone stay jailbroken after the firmware upgrade?
  2. Will I have to use tinyumrella to keep the old baseband, or can I upgrade to a new baseband (YES I WANT TO KEEP ULTRASNOW UNLOCK)

I might consider jailbreaking if I can still apply firmware updates without having to keep jailbreaking after each release. A major breakthrough.

I know this has probably been asked before but I really haven't got an answer. My case:

  • iPhone 4
  • iOS 4.02
  • Baseband 1.59
  • Not activated

Can I safely jailbreak and unlock today? if so, what are the steps and can the phone be returned to factory settings if needed? Is it true that the phone has to be activated with AT&T first? I certainly hope not! Thanks to anyone who takes this!

Beanboy, use TinyUmbrella to upgrade to 4.1 and keep your Baseband at 1.59.00. Then use limera1n or greenpois0n to Jailbreak as both hactivate. Then go into Cydia and get ultrasn0w to unlock. Check out the forums for more in depth instructions...

To be clear. You will ALWAYS need to rejailbreak after updates, unless you use custom firmwares that are pre-Jailbroken. There is no way around this because the way firmwares work is by literally installing everything from scratch, and erasing any previous software. Thats why you need to resync every time too. Gotta pay to play!

Wait, so this says Apple A4... only? Does this mean my 3rd Generation iPod Touch will not be safe from future firmware?

I was gonna update to 4.2 for the individual text alerts but now biteSMS has it. So I think I'll stick to 4.1 unless apps start requiring otherwise.

Thats why geohot jumped infront the dev team cause we won't need a new jailbreak. Still a d!ck move though
