I recently upgraded to the 3.0.1 firmware and, while HapticPro worked for a short time after this, it no longer works now. I have removed it, reinstalled it, disabled/enabled the extension through Manage Rock Extensions, restarted phone, etc. The program shows as installed, but I see no HapticPro listed under Wallpaper in the Settings section on the phone. As such, there is no vibration feedback from the keyboard or any button on the phone. Please advise, as I love this application.
When I upgraded to 3.0.1, I had to re-install all my jailbroken apps, even the RockYourPhone apps. After that, all my apps showed up again (and they kept their settings).
That being said, I have had real slowdown issues with Haptic Pro since 3.0....so I don't use it anymore. Bummer.
