Many blind people are already successfully using iPhones. The experience could be better of course, but many apps work really well (I will admit I haven't tried FB Messenger, and don't currently have an iPhone to hand). This would actually create a nice loop, and it would (hopefully) make app Devs take supporting blind users more seriously.
