DISCUSSION
I hate to point out the obvious, but it's impossible to get video output from anything non-media-player apps (like the Messages app) unless you Jailbreak.
In otherwords, they couldn't have done that segment without Jailbreaking the phone — so there's no way to tell whether they jailbroke just for that purpose or not.
