I have a theory, the iPhone 7 is the true Slytherin heir...
first "iPhone 7" is a very unusual name for a phone, what does the number 7 remind you of? Horcruxes of course! Voldemort split his soul to seven pieces!
Second, apparently people (or muggles) are hearing "hiss" sounds, guys this is the iPhone speaking in parseltongue, calling its master...
Third, the iPhone 7 and 7 Plus come in two new colors, what are the colors? Black and jet black! And voldemort always wears a black robe...
And lastly, The only new stock wallpaper in iOS 10 is a green waterfall, green is for slytherin.
Apple is slytherin, and the iPhone 7 is the slytherin heir.
Edit: OH AND ALSO, The apple, in the old testament was a tool the devil (THE SNAKE) used to lure eve into the sin! Apple! snake! Are you getting it???
