CTIA President Steve Largent said he has no problem with U.S. wireless carriers aggressively attacking each other in their advertising and marketing, and said the "sharp elbows" showed that there is healthy wireless competition. In an interview with AllThingsD, the head of the wireless industry's trade organization pressed the case for wireless spectrum, which the CTIA has been lobbying for. He also declined to talk about the marketing barbs that carriers are tossing at each other over the "4G" moniker for their wireless services. However, he did say he thinks the transition from 3G to 4G is going faster than the transition from 2G to 3G. Article
