I was messing around with my new phone and I entered the code wrong three times.. not sure what I was trying to figure out. But I did, and now it says Locked SIM at the top. It still works both on Wi-Fi and on the Verizon network.. although when I have Wi-Fi off, it doesn't say anything (no 3G, Verizon, or any bars). What does Locked SIM even mean..?
