A loyal reader recently sent in a tip asking us had we seen a dialog in Mail.app. The dialog in question is produced when creating a new note and pressing command + b. You would expect it to be a shortcut for bold, but no ... it brings up the above dialog.
The dialog specifies that by converting the note to Rich Text, devices such as the iPhone will not be able to edit it. Could this be a sign that notes syncing between iPhone and Mail.app could be coming in the not so distant future? We can only hope so.
Thanks for the tip, Shayan!
Update: As some have mentioned in the comments, iPhone notes syncing was an expected, but not released feature of iPhone 2.0.
