Don't let the results deceive you, though. Find out why after the break.
The survey didn't look at the amount of sex that smartphone users were having, it looked at the number of partners they had. And that number for iPhone users was 10 for men and 12.3 for women. BlackBerry users came in second, with an average of 8.1 for men and 8.3 for women. And Android users? Both men and women averaged six apiece. A second graph shows that the trends continue as users get older; while all three groups show higher numbers as they age (as you would expect), the iPhone still comes out on top (no pun intended).
So, this doesn't mean that iPhone users are getting more action than other smartphone users; it just means they collectively have more partners than the others. I find it comical that female iPhone users are the highest ranked group in the survey — I guess geek is chic — and attractive!
