A recent ChangeWave survey suggests demand for the iPhone 4S is still high six months after the handset launched. ChangeWave surveyed 4,413 consumers and 56 percent of future smartphone buyers say they plan on purchasing an iPhone. This is up two percentage points from a previous survey conducted in December 2011. During this same period, demand for Samsung's phones stayed the same while Motorola slipped one percentage point.
