UTStarcom PPC-6700 / XV-6700 / HTC Apache

I like the 6700 and cannot decide between that and the 700W. I use the phone on the road alot and the ability to use with one hand is a help for the 700W but could be a problem for the 6700. One of my main concerns was the touchscreen dialing, the buttons seemed kind of small and tough to press correctly when trying to dial. Does anyone know if you can change the screen to make the buttons larger or if there are different skins for the telephone apps on the 6700?

Thanks
