...and Verizon refused the 1st iPhone offer from Apple....business blunder of the decade.
That statement shows you know nothing of running a business.
There is a such thing as too much growth too quick, as AT&T full well experienced. Their reputation is tarnished, and it'll take years for it to be repaired.
Verizon, on the other hand, has had positive customer and revenue growth every single quarter since the iPhone was released. More importantly, they're on the other end with a reputation for being a solid company.
The iPhone may have actually cost AT&T more than it'll make for AT&T in the long run.
