While AT&T on Wednesday credited sales of 1.9 million iPhone 3Gs for helping to drive its fiscal fourth-quarter results, rival carrier Verizon won’t tell how many BlackBerry Storms were sold in its first quarter on the market; I wonder why? Embarrassment? Secrecy?

AT&T have announced full-year earnings per share of $2.16, up from $1.94 for 2007. The Dallas-based telecom giant posted $0.41 earnings per share (EPS) for the fourth quarter, attributing it directly to its partnership with Apple and the iPhone as the driving force for the gain.

Company quote: “Fourth-quarter EPS reflects the success of AT&T’s iPhone 3G launch. AT&T activated 4.3 million iPhone 3G devices in the second half of 2008 nationwide, including 1.9 million in the fourth quarter. About 40 percent of iPhone activations were for customers switching from a different provider.” Note that last part…absolutely huge for any part of any service sector.
