I have never had a smartphone before....because we have a Verizon plan...and because Best Buy is offering a free Droid Incredible.... I don't fully understand data plans...voice plans. Right now we have a 700 min family plan with an unlimited text plan. There are just 2 of us and I would be the only one with a smartphone. Please explain to me....I'm not sure I understand the Wifi and data plans....we have Wifi here at home through our cable company,.....can I get the $15/month data plan through Verizon...and use out wifi from home to cut down on how much of the data plan I use? Thank you!!!!
