OK so this first started on a 2g touch running 4.0. everything was fine but then the themes started acting weird. it would show the whole theme except the changed app icons that went with the theme. i tried many themes, deleted all themes installed new ones, deleted and reinstalled winterboard, none of it worked so i upgraded to 4.2.1 and rejailbroke. I got cydia again, installed winterboard, got some themes and still. no new app icons with the theme. what can I do?
