Wow, this makes absolutely no sense at all, but for whatever reason the WP developers have decided to remove the FM Radio feature from WP8, meaning that no WP8 devices support FM radio (or even have a FM radio chipset at all). Sure there are plenty of Internet Radio streaming apps, such as the promised Pandora radio, tune in radio, XboX music and of course the amazing Nokia mix Radio; but why on earth would you remove features in a platform upgrade? What is there to lose?

It is possible that Microsoft removed it to somehow increase traffic to the Xbox streaming service, but that seems highly unlikely; FM Radio isn’t a real threat to anyone (I’ve never used it on any of my phones but that’s mainly because all radio stations in Jordan suck).
So who said that Wp 7.X would be missing out on all the good stuff? Maybe MSFT did this to make early adopters feel better (that was sarcasm BTW).
