Probably go back to IOS. However, I'd send continuous emails or whatever to make sure Microsoft knew how frustrated I was with them giving up on Windows Phone. Everyone has a iPhone or Android phone, part of the reason I came to WP in the first place is because it was new and refreshing, it was in a league of its own. When I first saw that Lumia 920 commercial with the wedding scene in the movie theater, I was like "I'm tired of IOS, but I don't want android, Windows phone it is." Plus I always liked people not being able to recognize what kind of phone I have, but I would give up that last luxury if it meant windows phone receiving the attention it deserves and as a result, gained the market share it needed to prevail.
