COOL WAYS TO USE DATA
Show them Pandora (3 bucks a month for a FAR superior service compared to sprint radio)
Show them NFL mobile and NFL network.
Show them how good the web experience is when using opera mini (go to operamini.com from the phone browser and install it)
Show them how they can rent movies over the phone and watch them for 24 hours with sprint movies.
And last but not least.. show them porn.. lots and lots of porn.
I find that having one regular, one les, and one gay scene really gets all possible demographics interested... but if you live in San Fran, you could whittle that down to just one format.
