Ok, I'm new to this whole Blackberry thing. I have the Curve 8330, and have used my desktop manager >app manager to upload a theme to my device. It shows up in the options>advanced>applications field but not in the options>themes. What am I doing wrong? Yes: its compatible for my device.
First do a battery pull. If that doesn't work, I know you said the theme is compatible, but if it's in the app list and not under themes, it's either not for you device, or not for your OS.
