We have released a detailed tutorial on how to jailbreak the GM developer build of iOS 4.3. Yesterday, Apple seeded the final developer build of iOS 4.3, and the public release of 4.3 will take place on March 11th.

People are wondering if Apple has patched the current jailbreak exploits in their latest version of iOS. Because the iPad 2 runs on different hardware, it will almost definitely need a new exploit for an untethered jailbreak. As far as the iPhone and iPod goes, we’ll keep you updated…

If you’re a registered Apple developer, you can jailbreak the iOS 4.3 GM build with PwnageTool 4.2.

Our tutorial requires not only the developer GM build of iOS 4.3, but also a Universal Ramdisk Fixer and tetheredboot utility.

Again, you cannot currently get your hands on iOS 4.3 if you are not a developer. And the PwnageTool jailbreak is tethered, which means that you will have to re-jailbreak every time you reboot.

In our opinion, it’s not that big of a deal if the 4.3 GM can be jailbroken. What we’re really concerned about is the public release of 4.3 that’s coming next week. Hopefully we won’t have to wait for months before there’s an untethered jailbreak made available.

You can read more about iOS 4.3 here.

Do you think we’ll see an untethered iOS 4.3 jailbreak soon? iDB will be keeping you updated with the latest developments.

    I think untether will be quite fast compared to 4.1 and 4.2.1 Mostly because Comex is releasing his next tool when 4.3 is out and because the devs have been preparing for this one a really long time.

    Maybe it be best to wait for the 5.0 release huh?

  • MrE

    Kudos to Apple for keeping the 4.2.1 locked for such a long time. No one has been able to unlock it so far! Even if an unlock is found, it may be nearly impossible to unlock 4.3.

  • AMO

    Give us an unlock for 4.2 bb 3.10.01 first and then we can give a suggestion bout 4.3!!

  • Amit

    Pls..Give us an unlock for 4.2 bb 3.10.01 first and then we can give a suggestion bout 4.3!!

    Remember everyone that this uses the bootroom exploit which can’t be patched by Apple as it’s a hole in the hardware and that’s why it’s a tethered boot. It is nice to see it put together (with duct tape) so quickly though.
