Fee Panic Button (Personal Guardian)

Stay safe with Personal Guardian, your personal safety app for your BlackBerry®. Personal Guardian is a one push panic button that can silently send out an emergency email and even a Twitter message with your location information.
Whether you are walking down a dark street or just feel uneasy walking alone, have your finger rest on your BlackBerry®'s Convenience Key, and be ready to trigger off a silent alarm.
When pressed, the silent alarm will:
* Dial 911 (or configure a number of your choice)
* Send out a Twitter Message with your location information
* Send out a Email with your location information
* Send out a SMS with your location information
After setup, Personal Guardian also alerts you when an unauthorized SIMCard is used on your BlackBerry® Smartphone and will also turn on real time tracking.
You’ll also get access to the Personal Guardian web interface, where you can customize your settings and messages, manage your account and track your phone.
