Skype reported Tuesday it has logged 2 million downloads for its Skype for iPhone application, a bit more than a week after the application was released at CTIA. To get such a number, downloads have had to occur at an average of two to three per second since the app first appeared.

It's a big number considering that around 4 million iPhones have sold between product launch and the end of 2008, but you could dilute it down a bit if you throw in however many million iPod Touch owners may have downloaded the app.

Regardless, 2 million downloads in a week is still a big number, no matter how you might want to divvy up the pie between the total number of iPhones and iPod Touches sold. It is also likely a number to grow larger and be freely bandied about during Skype's lobbying efforts at the FCC and the EU, as it fights restrictions and/or banning of the application by carriers.
