my best friend's dad's ex-husband saw Steve cook at the Apple Store today in Georgia and asked him what the 'S' stands for in 6S and that's when cook told him.. "Now, say it again.. A little slower". 'sickss esss' 'sicks ess' 'sicksess' Duh! It means success! Wow hats off to crook and the whole Apple team for that one! It's like finding a new feature about or iPhones - who else is excited about this?
