I am running the new Hedone Design Biston theme, and it's pretty hot. Two things you gotta look for are the battery meter and cell signal meter. I think those two items are some of the main reasons this theme is so stunning. The color looks great on the 9650 and the 9700 devices I am running it on.

Biston is fast theme with animated menu in circle as you never saw before. You have 9 user customizable icons on home screen, big and readable battery and signal meters and TodayPreview for your future calendar events and new messages etc. Fonts in lists are user customizable and can be changed to what ever size you prefer. You can not change Menu font! Theme is made by HDTP. 

Theme also includes DFK (Double Function Keyboard) and was XtH tested. IMPORTANT: You MUST have a data plan/internet access on your BlackBerry in order to install themes. 4.5 version themes will NOT work on any device running an older operating system! Also 5.0 version themes will NOT work on device running an older operating system! Be careful when choosing, you choose one you would like to get! Subsequent claims can not be taken into account! Also check screenshots first and then select the theme you want!

This theme is well worth the money, and you can grab it here.
