iPod Touch Winterboard Theme

[Austneal]

I have a jailbroke ipod touch 4, and recently downloaded a new theme that is supposed to replace the battery icon(s) on the lock screen with custom ones. But when I installed and enabled it, nothing happened. I emailed the developer, and he said it was because of the 4th gen's HD display (but didn't act like he was in a hurry to update anything) Is there anything I can do to make this work?

Here are all of the pics, etc. that were in the theme folder
