mirror imaging ios5 iphone 4
I was at a tech seminar today and the Apple guy was talking about mirror imaging on an iPad2 to AppleTV worked great. He said it also worked with iPhone 4S. People with iPads and iPhones logged in and could over take the imaging which he said no problem try it out. At the end people with iPhone 4 said they could also do it. When I got home I tried it with my iPhone 4 and the imaging button appears and it has a check mark by my AppleTV but no mirror imagining it only streams my music. I'm thinking the audience members that thought they where on at the seminar must have not really been mirroring to the AppleTV and since there were so many people there they just got confused. Am I right that only the iPhone4S can mirror?
Thanks,
AppleTV 2
