The new AT&T is all about wireless and mobility, the company’s CEO said Tuesday during his first major keynote address since taking the helm earlier this month.

During his speech at the NXTcomm trade show on Tuesday, Randall Stephenson launched AT&T Video Share, a service that allows users to send live video feeds to friends or family while they’re having a conversation. Stephenson also talked about plans for the much-hyped launch of Apple’s iPhone, which will be sold exclusively for AT&T’s network.

The new service and phone, which combine the functionality of an iPod music player and a smartphone with email and other multimedia capabilities, are part of AT&T’s strategy to focus on wireless and mobility. The company, which now owns the largest wireline and wireless network in the U.S., believes that mobility will be the key service that entices new customers, keeps them with AT&T and drives growth in new services.
