"Why is the carrier trying to downplay the effect of Apple&amp;#8217;s bandwidth-hogging smartphone?\nSource: Rysavy Research\nIn his keynote address at the CTIA&amp;#8217;s (Cellular Telephone Industries Association) big fall meeting in San Diego Thursday, AT&amp;amp;T&amp;#8217;s \n\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\t\tT\n\t\t\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t chief technology officer John Donovan denied that Apple&amp;#8217;s \n\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\t\tAAPL\n\t\t\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t iPhone is the reason so many of customers are complaining about his networks sluggish performance.\n&amp;#8220;I&amp;#8217;m well aware of what&amp;#8217;s being said in the press, in blogs, and on Twitter,&amp;#8221; he said. &amp;#8220;The iPhone has certainly played a role. But it&amp;#8217;s not the only device driving growth. We have a lot of people going from basic feature phones to quick-messaging devices and other smartphones, which is driving data usage.&amp;#8221; (link)\nBut his words were belied by a graphic he flashed briefly on the screen. We&amp;#8217;ve dug up the source &amp;#8212; a white paper published by Rysavy Research in September &amp;#8212; and annotated it with a couple iPhone release dates.\nThe chart (displayed full-size below the fold) shows an 18-fold increase in data traffic during a 28-month period when voice traffic grew only two-fold.\nIf there were feature phones and quick-messaging devices released at the inflection points corresponding to the arrival of the original iPhone (June 29, 2007) and iPhone 3G (July 11, 2008), we must have missed them.\nBelow: The large chart. \nSource: Rysavy Research\n[Follow Philip Elmer-DeWitt on Twitter @ philiped]"^^<http://www.w3.org/2001/XMLSchema#string>
