Mobile advertising firm AdMob released its monthly Mobile Metrics report on Tuesday, which included information on the hardware and software used by owners of Apple's handsets in the month of March. The data revealed that just 2 percent of all iPhone OS-based handsets that accessed the AdMob network were the first-generation iPhone.

Philip Elmer-DeWitt of Fortune Brainstorm Tech took the data one step further, and factored in Apple's announced total of 85 million worldwide iPhone and iPod touch sales. After it debuted in June 2007 until the iPhone 3G came out in July 2008, the first-generation iPhone sold 6.1 million units, which is about 7 percent of the 85 million total handsets sold.

"If 7% of those iPhone 1Gs are driving 2% of AdMob's traffic," Elmer-DeWitt wrote, "that suggests that nearly one in three is still ticking -- and visiting the Web."

Is that so impressive? It´s not been three years since they were introduced, and not 2 since they stopped manufacturing.

Shouldn´t there be less than 2/3 of them already dead, or obsoleted? I´d consider that pretty bad, but then again I don´t swap very often.
