So, today I realized if I got to settings --> Mail, Contacts, Calendars --> Fetch New Data --> select my iCloud e-mail that under the Pushed Mailboxes there is a Notes folder which I never created. I have my iCloud e-mail setup on my Mac with Apple's stock mail app and I don't see it there. Also, on the stock mail app on my iPhone if I open it and select my iCloud account under Accounts I don't see the folders app; it's only apparent when I go to the Pushed Mailboxes setting I mentioned above. This isn't a huge deal, but it's just something I found peculiar. Wondering if anyone has noticed this.
