AT&T says Internet access to its iPhone and other cellular device failed for a time Thursday morning in Arkansas.

AT&T spokesman Michael Coe says an equipment issue caused the company's 3G service to drop out in northwest and central Arkansas. Customers also complained about not even being able to access the company's EDGE network, a slower connection for mobile devices to the Internet.

Coe said Thursday afternoon that engineers were still examining the problem.

AT&T Inc. is based in San Antonio.
