Ron,
I'm pretty sure this is a NorCal requirement only. It is in our Supps, not in the CCR.
When I tried loading this app on my Motorola Razr, it failed. That was last year and I haven't tried again. RaceCaster recommends the X-grip with suction cup. I don't know if I trust the suction cup part, the the X-grip is pretty good. I will probably just Velcro my phone onto the dash--if I can get it running.
It has been suggested to purchase a pay-as-you-go phone with data plan and use that phone instead of your expensive iPhone. Don't give out your new number to your grandmother!
It will be interesting to see how the Spotter app handles incoming phone calls, emails, texts, etc. Perhaps I can call you while on track together to arrange draft techniques to get past Buzzetti!
