Fire and Ice Theme is a free skin for your device, which adds a striking background wallpaper to your BlackBerry.
The abstract image features a tree with the left half bathed in hot red and orange, and the right side in cold, stark blue.
The Fire and Ice Theme adds a similarly schizophrenic nature scene in the background of the applications menu. Unfortunately, that's about as far as it goes and there's nothing in the way of new icons or menu items to speak of.
If you're the kind of person who revels in the diversity of nature then you might enjoy the Fire and Ice Theme.
