I have an old SERO plan with unlimited Vision Access. It also shows on my bill as EVDO Casual. Once I get a HTC Diamond, will I be able to use Sprint Navigation without paying additional fees? Or if not Sprint Navigation, will I be able to install and run a 3rd party GPS turn-by-turn program?
Thanks for the help. Waiting anxiously for the Diamond to show up in Sprint stores before finally upgrading to it.
