Tim CookOther Apple executives have been on Twitter for a while, and today CEO Tim Cook sent out his first tweet mentioning that he visited retail stores in Palo Alto for the retail launch of the iPhone 5s and 5c. Cook has been a member of Twitter since July, but his account is not yet verified by Twitter. Apple marketing chief Philip Schiller retweeted Cook’s tweet earlier today proving that the account is indeed run by the Apple CEO.

Earlier today Cook, along with Apple executives Phil Schiller and Eddie Cue, made an appearance at Apple’s Palo Alto retail store in California to greet customers that queued up for the launch of the new iPhones today.

Apple Marketing SVP Phil Schiller sometimes tweets about issues related to the company. For example, back in March Schiller tweeted the words “Be safe out there” along with a link to a study showing a much higher number of security threats on Android compared to iOS.
