I installed this hack a few days ago and it worked fine.
(It had to be installed because I dropped the ipad and the volume button was stuck permanently down meaning a) no volume, and b) the volume icon remains in the middle of the screen at all times - very annoying!).

Anyway, my daughter installed another theme yesterday and it seemed to wipe out the previous settings and the old trouble was back. She removed the new theme, still the same. I looked at the sources page in cydia and all bar one had disappeared. I found the sources, added them back in, reinstalled the volume button disable hack again....nothing. I removed it, re-booted, reinstalled.... still nothing. I seem to be back to square one, no volume, icon stuck on the screen.

Anyone got any ideas please?
