QuickPWN 3.0 beta 2 is known to work on iPhone 3G 3.0 beta 2, iPod Touch 1st Gen beta 3.0 Beta 2 and iPhone 3.0 Beta 2.

This software works with the RiPDev’s Icy App to complete the jailbreak process.

I know there are quite a few developers and even users who are eagerly waiting to jailbreak their newly installed iPhone OS 3.0. This is your best bet.

On the other hand the official iPhone dev team suggested users not to use the unofficial QuickPWN softwares to jailbreak their iPhones as it will kill yellowsn0w forever which makes it impossible to software-unlock your iPhone 3G [link]

iPhone Dev team has already announced that the iPhone 3.0 OS is jailbreakable on all devices, however, 3G yellowsn0w users will have to wait for a custom solution.

Here is the update and warning from the iPhone Dev team….

It almost goes without saying, but we will say it anyway

With all of the great stuff lined up for us with the 3.0 OS that Apple described today, many 3G owners may find themselves with itchy update fingers.  If you find yourself with access to the 3G IPSW for 3.0 via the iPhone Dev Center program, and you are using yellowsn0w, do not update or restore to that official IPSW.  You will lose yellowsn0w and find yourself unable to revert the baseband to get it back.

And for those wondering, yes the 3.0 OS is jailbreakable on all devices.   It’s just those using 3G yellowsn0w that have to show some restraint and wait for PwnageTool to create a custom IPSW that avoids the baseband update.

If you decide to wait a while before you update after reading the warning from the iPhone Dev team but still eager to know more about the updated features, Engadget has put up a iPhone 3.0 OS FAQ. Click here to access it.

I still can’t wait to see how Palm Pre WebOS does at launch.

Update: You can now officially download and upgrade to the latest version of iPhone OS 3.0 from here
