For one-handed dialing, even with the E-ten big-button hack I will often kludge around and press the wrong button while driving and dialing.
A good fix/solution for this problem would be a hack that would let would play/speak 1.wav when you press "1" (during the first dial out only), 2.wav when you press "2" etc. This way you could HEAR what you are pressing.
couple it with the vibration hack and you could hear and feel it.
Anyone know if this exists?
