Please guys... leave your password protection ON.
If you lose your phone somewhere (a bar, a train, a taxi) whoever finds it will have access to your email, your calendar, and all your friend/family contact info. That's bad.
I agree that the password entry is a pain, but at least for the safety of all the info that's stored on the device, turn on and use the password protection.
I picked a random combination of the 9 number keys (that actually become letters in the password) and I just remember what they are and I am able to enter them in 123-letter mode and in full qwerty mode.
