imageAT&T says it’s on-track to deliver the iPhone 4 to customers who pre-ordered the device on June 15.  And it says it will offer the smartphone to all other customers beginning Tuesday, June 29, when it goes on sale in all AT&T sales channels.

AT&T will send an email when each order has shipped. The company’s retail representatives will begin calling customers this week to let them know their iPhone 4 is available for pick up in store.

AT&T plans to have iPhone 4 inventory — available on a first-come, first-served basis while supplies last — on June 29 in its retail locations, at its web site (http://www.att.com), and in business sales channels.  As inventory sells out, AT&T will offer the option of purchasing iPhone 4 and having it delivered to a home or business or an AT&T store.  As always, customers will receive an email once their order is placed, and again when it ships.

To help customers stay up to date on iPhone 4 activities and important information, AT&T will post a series of videos beginning early this week at http://www.facebook.com/att .
