That didn't take long. Not at all. In fact, I've had my iPad in hand less than 24 hours.
Using Spirit, comex's jailbreak solution, MuscleNerd has already gained root access to the iPad. An hour ago, MuscleNerd tweeted the above video and said:
A public, nicely packaged, Cydia including, easy-to-use solution obviously isn't here yet, and there's still a definite possibility any release will be delayed until at least the 3G iPad hits stores, or 3.2 hits the iPhone, purely as a strategic move in the jailbreakers/Apple cat-and-mouse game that may or may not exist. ;)
Be assured though - it is happening.
