I did.
I'm pretty happy with the upgrade, the phone is nice, color is top (went from Space Grey to Natural Titanium) and the screen is gorgeous (I don't know if there's an improvement or if it's just a placebo effect).
BUT... for now the experience is pretty much the same as the 14PM thanks to this ridiculous take from Apple to postpone all the interesting new features. Other than the dark icons, there's nothing new.
