Just adopted my phone 5 days ago (Motorola DROID RAZR 16GB??) Can someone please explain the WiFi feature? Verizon Share Everything plan 2GB; 4G internet access & app Acess; Mobile Hot Spot Trigger... The guy at Radio Shack told me not to link it to my PC when I'm at home, but it does it by itself. He said something about using too much data space?? Also don't understand that the phone has 16GB and my plan has 2GB??? Any help would be appreciated!!!
