I connect with our exchange server at work and must have a passcode set. However, since upgrading to 3.0 I am told once or twice a day that my passcode has expired and I need to change it. I saw that some folks were having issues with a minimal lockout time for reentering their passcode and tried deleting and recreating that email account, but it still happens. Amazingly, I have not been able to find a peep on anyone else having this problem. Many of my co-workers have iPhones and connect just as I do and none have experienced this. Any ideas? Thanks!
