well i tried pretty much all the verizon phones at my local store the other day since i had to wait for a replacement for my treo...
what does your wife need/want in a phone? because my replacement was a blackberry curve - the curve probably the best phone for verizon, small, lightweight, full keyboard, email, etc.
theres really no touch screen phone i'd recommend from verizon. the lg voyager was probably the best one if u had to go with touchscreen, but they are all primative touch screens compared to the iphone, which i just got yesterday
