iPhone transforms AT&T network

The iPhone has certainly had an impact on customer's wallets, on Apple's Mac OS release schedule and on competitors like Nokia and Motorola. Now, it seems that the device has also had an impact on AT&T's cellular network. AT&T says that network upgrades go on all the time, but 20,000 new radios seems like a significant change for a single new device. The upgrades are having an impact beyond the iPhone, though--customer churn is low, and customer satisfaction is high. With results like these, the iPhone could prove important to AT&T for a long time to come.
