A Team Fortress 2 theme for the iPod touch and iPhone*...
Includes summerboard theme, carrier images, and battery images!
(Requires a jailbroken iPod touch.)
*Some iPhone icons are probably missing.
Note: If you're running winterboard on newer firmware, just copy/paste and rename some icon .pngs to cover unsupported apps as a stopgap measure.
Another note: For 2.x firmware, in order to get the battery working, you'll have to make a folder called "Bundles" inside the TF2 Theme folder, and in that folder make one called "com.apple.springboard", then put the BatteryBG_x.pngs in that folder.
