It’s not even officially available until Friday but super hackers the Dev Team have posted a video on YouTube claiming to have come up with a crack that will unlock any version of the iPhone with the 3.0 firmware – that would include the new iPhone 3GS.

The crack is being touted as ultrasn0w – an upgrade to the Dev Team’s previous hack yellowsn0w which unlocked the original iPhone firmware.

The Dev Team are keeping pretty schtum on the details for fear of Apple releasing a patch to counteract it.

I’m predicting that the iPhone will be jailbroken within hours of its release on Friday.
