I've got my ALL notifications turned on for my IMAP email account (which is set to check email every 5 minutes). That means I should hear a notification tone, I should feel a notification vibration -- and I should see the notification light. Absolutely none of those things are happening. When my phone is sleeping -- I get no light, no audible tone and no vibration. It very well may be operator error on my part -- but this phone is going back if this isn't resolved. Anyone else seeing this?
