Buzz has been building since the new iPhones were unveiled on Sept. 9 at an event near Apple’s headquarters, with pre-orders topping 4 million units in the first 24 hours and surpassing earlier releases. A third of Android users polled by Boston-based Gazelle said they’re likely to upgrade to the iPhone 6, with 39 percent saying the bigger screen was driving the decision. Last year, a 10th of the smartphones traded in when the iPhone 5s and 5c went on sale were Android-based devices, according to Chris Sullivan, Gazelle’s CEO.
