I (think) there are no themes to change the status
battery's colour only but not it's apple-styled shape. I was
frustrated trying to change its colour by a few themes but it looked
horrible. So, I made this theme including 10 colours: 5 for homescreen
and 5 for in-apps screen
p.s. it should be totally fine on iOS 5.0 or above but not on older
versions.
if you are in iOS 4 or below and have downloaded this package before
please do NOT update it.
