Ever since I updated to froyo, I have been forced to enter a 5 digit PIN or password to unlock the phone. In the settings, I can NOT use a pattern or use NO LOCK, it is grayed out and says: "Disabled by remote Administator". I have read that this is because I am connected to my works Exchange Email Server. Although it is a good idea, I like this feature, I wish I could temporarily turn it off. It is extremely annoying to try to hold a text conversation, having to constantly unlock the phone. I've tried apps like No Lock and No Lock Screen. They did not work. I want to be able to turn off the screen so I don't butt dial anyone, but I want to be able to turn it back on without entering a password. Anyone have a solution?
