Yes, all the buttons like your 'enhance / evolve / quest' buttons are all golden and shiny. The menu screen is all different too. They've just spruced the place up a little. No change to actual main screen though. One of my order mates says it runs a little smoother but I don't usually play on my android anyway, cos the iPhone seems to work better.
They did post an 'apology' on the home screen saying that you can clear the data and that will log you out (as above), but it sounds like a "Erm.... yeah, we were meant to have it like that"... after everybody kicked off about it. Cos why else would you get rid of the log out button eh?
