Email Notification Icon

I check all my personal email on the iPhone. If I left my iPhone on my table and then come back to it, the only way to know if I have a new email is to

Wake up the iPhone
Slide to unlock
Enter Passcode (Yes I use it and recommend others do the same)
Check the Email Icon

Too many touches and taps. It is sooo much better if iPhone could show the email status on the status bar at the top. Something like this...

This would show me if I had any outstanding unread emails with just the Wake up of the iPhone.
