since my area won't have 4g til the end of the year (according to my local verizon reps) i was wondering... will you be able to do the c2c thang via wifi if you don't have 4g? and i've never had a phone with ffc camera before so does anyone know how well the other video chat clients work (fring, qik, etc...) and if they work over 3g or just wifi?
