The iPhone will be the largest launch in the history of consumer electronics, according to AT&T's CEO Stan Sigman.

Sigman was speaking at the commencement ceremony at his former college, West Texas A&M University.

He discussed the 37 years since he graduated from the University, saying: "I never dreamed I'd be speaking to you now. I also never dreamed I would be part of the largest commercial product launch in the history of electronics."

He then revealed that the first iPhone had already reached Texas – Sigman had handed one across to the Dr O'Brien, president of the university, which he held aloft to cheers and applause.
