you should hard reset after new rom install itll get all the programs and also sprint nav just my 2 cents

one last thing you have to register with sprintpcs the sprint nav will ask for your username and password to let you use it
i also think sprint nav is way better than google maps i love it and once you get it running you will too.

i tried google maps and is decent in my opinion the only thing is that with google you have to be outside in order to get a lock and even then at least for me it takes too long so just experiment.
