A new plugin of sorts has recently appeared in Cydia which makes the iPhone Vibrate with each key press. This takes the iPhone 1 step closer to tactile feedback.
The application is named KeyVib and provides just a Toggle Switch to Enable or Disable the Vibration. The software is reported to not drain much battery and is pretty conservative in terms of battery usage.
KeyVib is currently available via the iSpazio Source.
Note : To use this Application you need a JailBreaked iPhone and 2.0+ Firmware !
