I bought several new droid phones for our group. We are on an exchange server. We cannot turn off the pin requirement. We have enter a code or shape every time we use the machine. We've gone into settings to turn this feature off, but it is greyed out so cannot be selected. Our Verizon sales guy says it is our exchange server forcing the droid phones (my razr and two other bionics) to require this. Anyone out there with same issue? Anyone know how to work around?
