While down slightly from a September survey, iPhone demand remained unusually high in December, according to new ChangeWave Research poll data. Of people planning to buy a smartphone in the next 90 days, 54 percent in the most recent survey said they were aiming to get an iPhone. While the number is down from 65 percent in September, ChangeWave remarks that Apple has never held such solid control more than two months after a major product release; the iPhone 4S shipped in mid-October.
