What do you recommend for haptic [vibration] feedback? Before 3.0 I used this hack I found, you copy 2 modified .plist files into the Celestial.framework folder. This made the perfect vibrations and didn't hang up, and even vibrated when the phone was locked/unlocked. I would like to use it again, and it still somewhat works, because I tried it on 3.0 and it vibrates when the phone is locked/unlocked. Have any ideas or other recommendations?
