Over at IntoMobile, they are reporting that "Sprint's Instinct is now the best-selling handset to have graced Best Buy's inventory in the past two years."
I wonder how many Instincts have been sold over this period? Doing a quick search didn't bring up anything. Q1 of this year there were nearly 31 million handsets sold in the U.S. and Samsung was number two after Motorola.
Putting Apple's iPhone in perspective, I believe they have sold 4 million so far, which is about what Nokia sells in a week globally.
