When it comes to BlackBerry themes, I don’t think there is any theme designer to push more themes out than the Indonesian developer IDBERRY. One of their more recent themes, MaemoVista is all scenic backgrounds and Windows styled icons.
I haven’t actually tested this theme out for myself but going by the screen shots, it looks slick. I do know there is a video you can watch at our store link, that should give you a better idea of how it works. In the meantime, you might want to check out some of IDBERRY’s free themes at their blog.
MaemoVista (a little higher priced than some of their other themes) is available for a variety of BlackBerry devices at our Berryreview Store.
