Sprint CEO Dan Hesse was speaking out about the HTC EVO 4G and its success on his company’s network today at a Forrester Customer Experience conference. After his keynote presentation, Hesse spoke with Reuters about their first 4G phone, which has been selling better than Sprint or HTC expected. New phone equals can’t meet demand. This is the same story with other new phones (HTC Incredible and Apple I Phone 4). Why can’t manufacturers predict what they are going to sell or have a surplus? This is the first 4g phone on the Sprint Network and and it has awesome specs (4.3″ screen, hdmi out, 8 mp camera, 1.3 mp camera on front for Skype, etc). It’s a no brainer; it’s going to fly off the shelves. Why not predict you are going to sell more than you expect? Only Sprint and HTC know the answer to this question. Some say that the shortage is due to the lack of supply of the screen. Hesse was asked if the shortage was due to component shortage and he said that demand has been higher than anticipated.
