This was initially placed into the wrong forum.... I have been with Sprint for about 14 years. I have had various phones with them, from various manufacturers. The one manufacturer that I like the most has been (I think) Samsung. They offered the BEST "security" if I may. I need an app that can provide the same thing... Does an app exist that will allow me to lock my phone from allowing incoming calls to be answered if my phone is locked, not to mention, I don't want who's calling me to be visible either. So what I am saying is that I basically want the phone to be a ringing brick until i use a code to disarm it. The phone manufacturer is Sanyo. Parental / Business Control Settings "Limit Use" - Restrict Incoming and/or Outgoing Calls to only the Phone Book entries or to 3 Special Numbers Please tell me that someone out here can make this happen or that it already exists. Thanks.
