    Unlock the phone using my SIM card number.

      I just bought a used HTC Radar 4G.

      I reset everything and started updating it using Zune.

      When the phone is connected to the computer,

      I got a message saying my phone is locked and so unlock the phone using my SIM card number.

      This is my first smartphone and third T-Mobile phone.

      I have never been asked to insert the SIM card number except for the first one.

      Without Zune, I cannot update my phone and others.
