Fancy Widgets is a cool little app that brings the widgets of other platforms to your BlackBerry device. It features an automatic wallpaper switcher, integration with BerryWeather and the BlackBerry Calendar, and many other nice visual tweaks. The BerryWeather integration (as pictured above) alone makes it a must have, in my opinion. Fancy Widgets really does add some nice customization to your device, and I have yet to see another app like it for BlackBerry.
You can pick up Fancy widgets on sale for $2.99 (40% off) at the CrackBerry App Store, until December 31st. It is compatible with device running OS 5 and up.
