Are all themes compatible with all BlackBerry devices?
No. Unfortunately not all BlackBerry themes are compatible with all BlackBerry devices. The compatibilty of the theme depends on the BlackBerry device model and the version of the BlackBerry OS which it is running. As you may know, there are many BlackBerry models available for purchase. Each BlackBerry device model can have one of several versions of the BlackBerry OS installed. To add to this variety, a BlackBerry device model may also differ depending on the network provider(i.e. ATT, Cingular, Verizon, etc.). Many of these variations require different versions of these themes with files saved specifically for them.
