Verizon Wireless chief Lowell McAdam at a Barclays conference today said that his company would be selling "twice the number" of Droid Incredible phones if not for a chronic parts shortage. He blamed Samsung for a shortfall in the 3.7-inch AMOLED displays that are used for both the Incredible as well as other HTC flagships like the Desire and Nexus One. Samsung was ramping up production but wouldn't keep up with Verizon's demand for another 30 to 60 days, McAdam said.
