When you turn on your phone, it shows the date and time junk at the top and the slide at the bottom. Does anyone know the exact area between the two displays? 320 x ABC? I like to make my own wallpapers but a lot of times they end up sucking because an important part of the wallpaper will be behind the slide bar or the date and time

. I looked around for it but no one seems to have asked it. Thanks.
