I’m now a BlackBerry owner due to the need to keep on top of my workload. I’ve got an 8900 and starting to play with it. Theme creation is pretty straightforward and the first attempt is here (colours_lights).
The theme is based on one by Dylan (found here) but of course I needed to prove to myself that I could do one the same and to play with it until it could be just as I liked it
