Last week, we reported that Apple's Phil Schiller has gotten a verified account on Twitter, and since then, his popularity on the short form social networking service has apparently skyrocketed. Rather than just retreat to the shadows, he's stepping up into the limelight, sharing insights and answering questions of all kinds from Apple fans. It's pretty awesome, actually -- he's sharing everything from his favorite apps to why you have to put in your iTunes password every time you install a new app (for security's sake -- Apple wants your approval for every piece of software on your machine).
