Dave let me know about his cool HTC Hero Sense theme for the Curve 8900. The theme is obviously a take on the HTC Hero, and has a very clean interface and smooth icons. The thing I dig most is the way the banners are laid out, with the notifications being on the bottom. There are multiple versions available such as Quicklaunch, Today, Weatherbug and various other combinations. If you're in the mood to check out a great free theme, definitely give this one a go.
