New to the forum... .. and got my first smart phone recently (D4) from Verizon but was reluctant to pay monthly for GPS navigation for something I'd only use sporadically. Installed Google Maps and it appears it will work without the added monthly expense. Since I'm new to smartphones and data plans, I'm kind of clueless to how it all works. I really don't use the phone all that much and only have 450 anytime minutes and a 2GB data plan. Any idea how much of what a 500 mile trip or 8 hours of using the Google navigator take? All is there an app that can send messages (to friends) and photos (to friends or Facebook etc.) without paying Verizon the added costs?
