Look! He is one of us! In an interview with Jimmy Kimmel, actor Justin Long (from “I’m a Mac” fame) showed off his iPhone, which clearly shows the Cydia icon on his homescreen. There’s also an amusing SMS exchange near the middle, if you want to see some surprisingly bad spelling.
Although, as the commenters at Engadget have pointed out, Cydia and TVOutTuner both seem to be the most recently installed apps, meaning that the show’s tech-guys may have installed Cydia in order to mirror the display on the big-screen. I like the former explanation better, we can dream, can’t we?
