ok i had 2 previous smart phones before i switched to bb. the shadow and the other one. sheesh forgot the name, touch screen. anyways when i didn't pay my bill on time, they would cut it off, but if i had my wifi on, i would still be able to use my phone. internet wise, receive email and browse, if i put in my simcard, im pretty sure i can use them. now i have bb, and i have wifi on, but i cant do anything. even tho my service is cut off. what's up with that?
