Are iPhones disrupting AT&T customers' service?

September 3, 2009 The New York Times reports that the average iPhone owner can use 10 times the network capacity used by other smart-phone users. The result, according to one analyst in the Times report, is an increase in dropped calls, sporadic service and delayed voicemail and text messages.

The paper interviewed AT&T customers who are upset by the iPhone overload. Analysts suggests that it could become a problem for other wireless carriers in the future as other smartphones get more sophisticated features.

AT&T says The New York Times report does not provide an accurate picture of its overall network quality.

AT&T says it is in the process of doubling its wireless spectrum in Chicago and throughout the country. It is also adding more than 1,900 new cell sites in the US to further improve coverage.
