I’m not surprised that Apple’s iOS lost to Android in sales units (17.3M vs 60.5M units), but very interestingly, it also lost to Nokia’s Symbian OS (19.5M). This is for Q3 2011. Okay, I know many people were holding off their iPhone purchase in anticipation of the iPhone 4S release (or they thought, the iPhone 5). But still, it looks like Symbian isn’t sinking all that fast.
