At work, we were having some problems with our new server which affected receiving email on my phone. Somehow while making changes on my phone with my work email, I enabled a screen lock with a password. Now when my phone sits idle for a little while and I activate it, I have to unlock the screen with a password. Under the Security field only "Screen unlock pattern shows." When I tap it, nothing happens. The next field is "Change Passwords." That only gives me the option to change the password. I don't want any screen lock on my phone. How do I remove it?
