AT&T's Emerging Devices lead Glenn Lurie in a talk today provided an extra view of the company's attitude towards the increasingly likely Verizon iPhone as well as some insight into the carrier's relationship with Apple. After being grilled repeatedly by Walt Mossberg at the D: Dive Into Mobile conference, he dismissed the multiple leaks as "rumor" but was confident it wasn't an issue. AT&T was "not concerned about it at all" and had many devices it could compete with, Lurie said.
