How can I do this? I understand the files are UIPageIndicator.png and UIPageIndicatorCurrent.png in Other.artwork, so I extracted the images from Other.artwork, changed them with the equivalent files from the No Page Dots 3.0 package in Cydia and repackaged it, but the dots are still there.
BTW I did manage to change other files in Other.artwork and they do show up on the iPhone so my method is correct.
