I have a theme that I have set on my iPhone running 4.2. It was designed pre-iOS4 and is having a few minor issues. The names on my emails are just black bars and none of the media (audio files or videos) will load. It just goes back to the Springboard when I try. I can turn the theme off in Winterboard and all is fine, so I know its something to do with the theme.

Any thoughts? I like my theme and want to keep it.
