Do you set your phone to do an alert sound when you get email?

Poll question: Do you set your phone to do an alert sound when you get email?

I've had this happen with two older people now where I send them an email in the middle of the night, and in the most recent case, I got a response from my boss's blackberry at 6 am, and in the previous case, a guy was telling someone else I ''woke him up in the middle of the night with an email.''

Do you forward all your email to your phone and have an audible alert set?

If so, does it annoy you if someone emails you in the middle of the night?
