These are battery icons for the Apple iPhone. They will display while the phone is docked/charging. There are six color versions to choose from. Please don't use the pink one, it's ugly.
REQUIRES A JAILBROKEN iPhone!
How to install:
1. Download the zip containing all images here: [link]
2. Connect to your phone using WinSCP or the equivalent for Mac.
3. Navigate to /private/var/root/Library/Customize/BatteryImages/
4. Copy the downloaded folder with the battery images into the BatteryImages folder.
OR easy method (RECOMMENDED!):
to your installer sources. It will have the file so you can install it automatically. Once the source is added, browse to "iFon Themes" and install "LogoBattery". This is a Norwegian source, so just remove it when you're done to remove the clutter if you're not Norwegian.
If you want to do some changes to it, I have a really tidy PSD I can send upon request.
