It’s here. iOS 4.1 Beta 3 was just released to developers. I’m wondering if it fixes the PDF bug that JailbreakMe uses to jailbreak the iPhone…

As usual, you have no business downloading and installing iOS 4.1 Beta 3 if you’re not a developer. Jailbreakers and unlockers should stay away if they want to keep their jailbreak/unlock ability in the future.
