Checking through the forums today I came across the BeBerry (formerly known as PreBerry) theme for the Storm, Bold and Curve 8900. The theme has clean icons inspired by the Palm Pre and is laid out very well. BeBerry has custom menus and dialogs, customizable home screen icons and a custom wallpaper design. There is also a cool plugin to go along with the theme.

The innovative BeBerry Theme Plugin, launched via the About button, gives details of your Blackberry Smartphone including Battery level and free memory available. We plan to ehance the plugin with new features and functionality including, where possible, those requested by BeBerry customers via the Feedback menu on the About screen. Join others now in helping to shape your theme's plugin features. 

You can grab BeBerry for the Storm, Bold or Curve 8900 at the CrackBerry App Store for $5.99.
