It's interesting that this understanding exists. To note a few case: the Windows Phone was awarded the most intuitive phone, and another one that said it's the best phone for people over 50 (or 60?). Also user satisfaction is right up there with the iPhone.

What do you think about Android? Personally I find it confusing with menu lists in several places (apps, settings, etc.). The iPhone I agree is very intuitive. And I tend to think the WP is even simpler.
