Blackberry Phone Record

I need a Blackberry application created that will enable a user to press a certain button on the phone to record the phone call. ## Deliverables I would like a program to be developed for Blackberry phones that will enable the user to press the enter key while on a call and it'll record the conversation to the phone (media card).? I know the Blackberry Storm is all touch screen so the user will need to press the keypad button then a button on the keypad to record.
