Please let me know if you have permanently solved your stuck volume button. I'm almost ready to drill into the volume button and pull it out or jailbreak my iPad2.
I really need a solution, beyond paying Apple repair $350.
Have you found a permanant DIY repair method? Or, have you successfully jailbroken to install the "Volume Button Disable" app from Cydia?
P.S. It's my volume-up button, and subsequent on-screen volume icon, that is stuck. The slightest bump, rotation, or even picking up the iPad2 jacks the volume to Max, as if I were pressing the volume-up-button.
