A loyal (some would say awesome) reader sent in their experience of jailbreaking an iPhone 4 at an Apple retail store and captured the event on video. He obviously used www.jailbreakme.com to do the job which opens the door for 3G FaceTime and hotspots and customizations.
While jailbreaking is fun, but a pain for store employees to have to re-image every night, a more fruitful prank would be to set all the Mac web browser home pages to 9to5mac.com. Video or it didn’t happen!
Thank you, Ethan for the video!
