I am going to try and fix a friends iPad2 that she says her son dropped and now the volume is stuck pressed all the way up. The volume shows on her screen and she contacted apple about fixing it they want $250 I know I could fix the rocker by removing the screen but I have done this before and I know it's a heck of a job.. So that brings me to my question. Is there a way to disable the rocker and just do an onscreen volume using a jailbreak app?
