I make several calls that require me to enter additional tones on the keypad, and hate that I have to open the keypad, or worse, have to unlock the phone first, then open the keypad. Is there an app that will allow me to keep the phone keypad open during calls, or is there a setting somewhere I can change to do this? My fiance has an iphone and when you move the phone away from your ear the keypad opens. That would be a cool option for the Hero. Thanks in advance for the responses.
