Apple Inc. remains on track to ship the first of its iPhone mobile handsets in the U.S. by the end of June, a high ranking executive for wireless carrier AT&T confirmed Wednesday.

"Our expectations are good. Our testing has been good," said AT&T Chief Operating Officer Randall Stephenson. "The iPhone is on target to launch in June."

Stephenson's comments come in the face of recent and unsubstantiated blog reports, which speculated that the touch-enabled mobile communications device could be delayed due to technical issues.

Speaking at a Boston College Chief Executives' Club luncheon attended by Reuters, the AT&T exec reiterated that his firm, which has an exclusive deal to sell the highly anticipated Apple handset in the U.S., has received over a million inquiries from customers eager to purchase the device.

At the same time, however, Stephenson could not say how many iPhones would immediately be available upon launch.

"We're sorting through that right now," he said. "We got a million people waiting to buy it so we're hoping we get a million."
