I have been looking everywhere, I tried a few on cydia just to test it out but I cannot seem to find a custom battery charging theme that works with iP4. I just want it to disect the file structure to create my own. Do these custom battery charging themes even work on iOS4 anymore, because you can still download them in cydia but so far I haven't found any that work. There are a couple tutorials on youtube to create the images, which I did but now I am thinking that you need a 2x version to make it work on iOS4. I have my own images so maybe I will test that later. Has anyone successfully made their own or got one to work on 4.1+ PLEASE HELP, any info you might have to shed some light on this, I am so desperate to get this working!
