New iPhone 6 - hints in Notifications I have been receiving new iphone 6 hints in my Notifications but when I go to try one out and go back to read it again it is gone. 

How do I retrieve them and where do they do they come from?
They are from a new app called Tips, added with iOS 8.

It will post occasional tips &amp; tricks on your lock screen, but you can launch the app itself &amp; browse through them any time you like.
