wallpaper question

Hey all, I have had my blackberry pearl 8130 for about a month or so now, and I have downloaded themes and wallpapers and all those other good things, I currently have the bphone theme running and have changed my main wallpaper, but my question is can I change the wallpaper on the screen where my phone is locked, because I have my main wallpaper, but when I lock my phone it is something completely different. Thanks

i've found that some themes let you change the background, but some do not. it depends on the developer...
