Shift by Elecite
If you are familiar with themes from developer Elecite, you know they stand for quality and originality. Each of their themes are handcrafted for superior function and style. Shift is one of Elecite's newest themes, and it is packed full of awesome features spread across 3 panels and 3 pages so you may never need to see your app screen again to find what you're looking for.

The first panel displays your 5 top icons, 4 popular standard icons, a weather slot (for BlackBerry Storm and Torch devices) and a Today preview so you won't even have to open your messages and calendar apps to view their contents. Panel #2 makes viewing Media extremely enjoyable. 5 icons get you to all of your Pics, Music and more instantly with customizable icons when you need them. On top of that, the Utilities Panel brings up all of your apps, quick notes and calculator. A bonus dock with 6 customizable icons allow you to make this tab extremely personal.

Overall Shift is a beautiful theme and once you get used to the layout I think it's a theme that will add a lot of efficiency to your device. Elecite also has a pretty good customer service department. If you have trouble with your theme after purchase, contact them and they will do all they can to be sure you're satisfied. Shift is available for $6.99 in BlackBerry App World and is compatible with BlackBerry 8900, 95xx, 96xx, 9700, and 9800 (OS 4.6 to 5.0 except the Torch).
