so i unlocked an iPhone, synced it up yada yada yada and went to call someone on my family plan and it displays Voicemail as the name you are calling!!! the call actually goes through to whoever i am calling but shows Voicemail as the name for the entire call... however, if you go to the keypad and type in the number manually it displays just below the number the name of the person you are calling in small letters, but still when you hit SEND it goes right back to displaying Voicemail as the name and still calls the number assigned to that person... what gives?
