I'm working on a theme, but of corse I can't make a different icon for every app. So i decided that I wanted the icons that i couldn't change to have no glare/ gloss. But I don't know how to do this on 3.0. I've tried a number of things:

Putting <key>UIPrerenderedIcon</key> in the info.plist
<true/>

Adding transparent appstoresadow.png and appstoreoverlay.png into the UI Images

and used the "No Glare" theme from cydia.

All 3 have failed and something tells me it's because of the 3.0 software. So if anyone could help me that would be great.
