All we can say to this is - bwwwwwwaaaaaaaaaaaaaaahhhhhhhhh!
To coin an annoying, but popular phrase from the webiverse - Apple just got pwned. Yep "pwned". It's what all the cool kids say apparently. If being cool is sitting in your bedroom all day on internet forums that is.
Anyway, back to the matter in hand, this video shows off the audacity of Ethan Zachery, who took jailbreaking to the extreme by rooting an iPhone 4 at an Apple Store.
Zachery used the Comex jailbreak method to carry out the jailbreak and, although he sounds a little bit scared of being caught by the Apple staff, he carries out the process with a cocky-coolness that we at Pocket-lint applaud.
It's a bit like Project Mayhem in Fight Club, except no-one has to drink urine or get blown up.
Imagine the Apple Store employee who demos that particular handset to a potential customer and has to explain that many of the features on offer won't actually be available if they buy an iPhone 4.
Well played Ethan Zachery. Your web 5 minutes of fame has been well earned.
