I was out last night with a friend when the two us met a guy at a bar in Manhattan. He saw me pull out my iphone to check a text and that was when he mentioned he worked at Apple. I use a passcode on my iphone and he said he could "guess" my passcode if locked my phone. I locked my phone, handed it over, and he was able to somehow either guess my passcode or bypass it somehow within about 3 minutes. He handed the phone back to me and I immediately changed my passcode-- and handed it to him again. He was able to get in again within about 5 minutes this time. I could not see how he was doing this and he left shortly after performing this trick. He wouldn't tell me how he did it. How?? Is there some type of "master code" that Apple technicians use to get into people's iphones to repair them? Or, are passcodes just really easy to hack? I don't know in what capacity this guy works for Apple--I assumed he worked at a local retail store as I didn't think Apple had any offices in NY.
