There are plenty of stories coming out of Nokia’s much-anticipated introduction of the Lumia 920 this morning, so I’ll use this space to direct your attention to some compelling new data from comScore regarding the upcoming iPhone. As Mobile Marketing Watch reports, the vast majority of owners of recent iPhones are planning to buy Apple’s newest handset, and substantial percentages of Android and BlackBerry owners plan to switch. Meanwhile, a hefty 32 percent of users who don’t yet own a smartphone are eyeing the new iPhone. And Apple has grown its market share in recent months even without producing a new handset. All these signs point to huge sales for the upcoming iPhone, which is slated to be announced next week.
