If you thought only Android smartphone makers like Samsung are interested in curved smartphone screens, better think again. Apple was, in fact, thinking of something even more radical as far back as 2011. Cupertino was just granted a patent for an "Electronic device with wrap around display" that does exactly what it says in the text. It has a screen that goes from front to side to back to side to front again. Like a double-sided Samsung Galaxy edge, but an iPhone, of course.
