I like to set reminders on my pre installed calendar that comes with the Droid. If I happened to not be near my phone when the notification reminder alarm sounds, a few minutes later I will hear another alarm telling me that same reminder can now be found in my Gmail inbox. Now I went into my Gmail settings for the calendar yesterday and I turned off all notifications pertaining to email in Calendar settings. Today the same thing happened as if I never turned those settings off! I am not sure why if I missed the reminder on the phone why it sends it over to my the inbox of my Gmail account.
