Looks nice. Only thing I have found that was odd afterwards was logging in using the 'Mobile' setting (on a PC with Firefox) and the using the Apple iPod style the display is garbaged at the top. Doesn't have a problem with EDGE or Windows Mobile theme. This is on my test server.
**Guess I should also mention I did a 5.0.9 > 6.0 upgrade a few weeks back without any problems.
