It’s way buggy still, but hats off to jailbreak hacker David Wong who not only figured out how to get the iPhone to dual boot, but to actually run Google’s Android operating system.
Of course, the entire exercise is one of utter futility — why would you run Google’s inferior Android operating system when you can tool around in iPhone OS (my only tentative answer: maybe tethering?) — but even so: this takes some brain meats. Well done, sir.
