Apple says it has sold 5 million iPhones over the weekend, outdoing its sales for the iPhone 4S last year by 1 million units. Despite the ho-hum reactions by some who noted that the new iPhone isn’t anything revolutionary, the lackluster Apple Maps application and the fact that Samsung still leads the market in total smartphones sold, the iPhone 5’s huge launch swings the spotlight to mobile advertising, especially for those who have somehow ignored the trend so far. Mobile-optimized sites and emails, and a mobile ad “pilot” campaign are among the things that should get late marketers started. (CNET News, ClickZ)
