Ive been trying to theme my lockscreen and I downloaded the tap to unlock from cydia as a guide for iPhone4. Usually you just change the bottombarbkgndlock.png to a transparent blank image and the bottombarknobgrey.png to your tapper. In this theme however there's two images for both. They are the same image but one is double dimensions and has @2x at end of filename. Im assuming i'm only replacing two images on my iPhone not 4. So am i correct in assuming that the @2x file is for iPhone4 and the files w/out @2x are for anyone else with an iDevice other than iPhone4 that downloads the tapper package? Also, the red, green, and grey tappers have files named bottombarknob(color)@2x.pngBK. What is the pngBK file doing? Secondly, I've been trying to theme the iPod music player(play, pause, next, volume slider) but can't. The stock 4.0 themes are completely wrong as far as i can tell and i don't know where to put my files for the music player. Can somebody give me a filepath for where to put these or does anybody not know because no theme's filepath(even those claiming to work for iphone4 in the iphone4 theming thread)have worked at all. Any help is appreciated, thanks.
