I am from Taiwan. I'll visit San Francisco in January and I will drive from Las Vegas to Grand Canyon National Park.
I'll download Navigon app on my unlock iPhone 4 and buy the AT$T goPhone pay as you go sim card.
Should I buy the data plan too for Navigon navigation??
Someone told me that I can turn on the 3G connection for GPS and turn off the cellular data connection.
Is that OK???
