hi all I have elite HD beta on my iphone 3gs, when i open an apploication before it opens i get a black screen with the writing Starting and a red loading line

I would like to change those wallpapers to the one I am making,

so i made one for skype, called it Default.png and moved into EPHD 3G.Themes>Bundles>com.skype.skype after respring the wallpaper change so when i open skype i see my own wallpaper,

but this does not work for all my other apps like facebook messenger etc it only worked for skype and twitter, anyone know why?
