This one is a bit hard to explain, but it is getting to be annoying.
If I receive a new email, I get the notification sound. After reading the email, then putting my phone back to sleep, I get another email notification sound. The problem is, there are no new emails when this happens. If I read more than one unread email in the same session, then put the phone to sleep, I get a notification sound for each email that I read.
This seems to have started at the same time as the 2.2 update. Should I delete my exchange settings and re-enter them?
