I was looking at the manual for my Samsung Galaxy Indulge and PIN is supposed to be an option for the lock screen, but all I have is pattern and password.. I want to add my exchange address and the activesync policy only requires a 4 digit password and allows simple passwords, doesn't force alphanumeric, but PIN isn;t an option on my lock settings.. Even before I set the e-mail up. The manual claimed PIN should be an option. I know Pattern won't work with activesync password policy which is lame, but a 4 digit PIN wouldn't be too bad. That's what I have on my iPhone with my exchange mail sync'd.
