Following on the heels of -- and almost precisely in line with -- a Comscore study of US marketshare, ad network Chitika reports that when looking at just the "4G"-capable segment of the overall smartphone market, the iPhone 5 (Apple's only "4G"-capable phone) dominates web traffic just as the iPad does in the tablet arena. When looking at only 4G/LTE smartphones released since July of last year, the iPhone 5 by itself accounts for just over 75 percent of North America 4G web traffic, and when considering all still-active 4G/LTE smartphones it commands about a 40 percent share.
