This feature has been lifted from Diamond where the phone vibrates when a call actually gets connected so that you don't have to hold the phone to your ear unnecessarily.
This small utility has the foll. features :
1. Vibrates on Incoming / Outgoing calls
2. Vibrates only when the call is actually connected
3. Also vibrates when a call disconnects.
Tested on my Moto Q GSM.
'SmartPhones only' for now ...
Requires .Net Compact Framework 2+
