I bought a iPhone 4s from a friend, and both of us use verizon. She removed her sims card, and everything seemed to be working. My boyfriend thought he was helping and ended up doing a hard reset on it, and now it states "No Service" and will only let me go thru the screens to choose a "wifi network" or "choose another network" or "set up phone using iTunes". I do not have a wifi connection where I live, nor do I have an iTunes account. How do I get this phone up and running?
