I'm on Gingersnap too. Played around with the UOT kitchen the other day. Was able to change the 3G/1X icons (which are kinda ugly) but the battery ones wouldn't take. Also tried it with the center clock fix script, but it wouldn't work. My next trick was to add some custom-made PNG icons (38x19px, and pretty snazzy looking) to the SystemUI apk (though the dimensions were different than the ones I was replacing, but with the same exact file names). Result was that the status bar did not show up on top but some garbage showed up on the bottom of the screen. Still tinkering with mine, and may do another kitchen project. Also may decompile the apk and take a look at the XML script. I could possibly change a few things there. Still playing around with it.
