Really curious about where you got the data that Apple has 1 billion active user. I know they sold over a billion iphone overtime, but that's certainly not 1 billion different customers buying iphones. Also, I would assume a pretty big intersection of Mac or iPad users also own an iphone, so that wouldn't count as many customers either.
