This theme, specially made for the Bold and other BlackBerry devices, uses the BlackBerry 7 OS icon set, which gives your OS6 device a new feel to it. It's free, so try it!
EDIT V1.1: COMES WITH TRANSLUCENT TRAY AND ORIGINAL OS7 WALLPAPER.
To get the charging icon back, go to where the default files are saved on your computer (program files/research in motion...., I can't remember the exact location) and find the battery icon set. Copy it to a new destination, I used to use the desktop. Simply rename it to something simple like 'battery', then import it to your theme in theme builder. It won't have the flashing effect, but it will show a solid lightning bolt when charging. Hope this helps
