Morgan Keegan analyst Tavis McCourt on Monday warned that smartphone sales may have had their first absolute decline in the US. Studying AT&T results as well as those from Verizon, he believed that smartphone shipments dropped both quarter-to-quarter and the past year. The wait for the iPhone 4S on both carriers was the main factor, McCourt said, but he also saw a significant drop in Android and other platforms over the past quarter.
