Apps that can alter the default security policy can be powerful and handy, but you need to know why they are doing it before you say OK.

I purchased the Unlock with WiFi app that Jerry recommended a few weeks ago. I haven't fully installed it to use yet because it asked to "activate device administrator". I wanted to be sure that was OK? What risks does it create to allow this type of access to my phone?Thanks!
