Oh no. I don't like the new style at all. The icons look exactly like the Microsoft icons and I can't seem to be able to change the colour of the block at the bottom from that really ugly grey, or atleast make it see-through like the old version.
I'm using a 4S and things seem just a little bit less smooth than before. Also, for example, when you press the button on the top of the phone, for say - checking the time quickly, there's a little pause before the screen even lights up. And is just me who thinks the wallpapers have zoomed in a touch and become just a little bit blurry?
Not a fan.
