Maybe they could make a bluetooth keypad. it could be small and have 0-9, *, and #. This could also be a good solution to those who want to text the old way and would like something tactile to use so they can use it while focusing on something else(driving). It could also be used for dialing numbers while using the bluetooth headset. I wouldn't buy it but it might have a market and might make it easier for those who need that functionality to switch to iPhone.
