Here is a rather -major- upgrade to the "Q" theme up above. I have changed a lot of stuff. Upgraded wallpaper, transparent icon bar, settings, bluetooth manager, file manager, task manager, tasks, and calendar all launchable from the desktop / home screen. Definitely worth the download, if I do say so myself

. Unfortunately, no preview this time. If anyone can tell me how to grab a screenshot of the home page, I will happily post one up.
To Install:
1) Unzip the files to a directory of your choice.
2) Plug your Q in, and click on the "Explore" button on the toolbar.
3) Click on "Mobile Device" ( or whatever it is )
4) Navigate to Application Data\Home
5) Drag and drop the files from the zip file into this directory.
6) Go to Start->Settings->Home Screen on your Q.
7) Select "The Q Full Layout" for your layout, <default> for your color scheme, and <default> for your background.
8) Hit "Done" and return to your home screen.
Enjoy!
