so far, it doesnt work for my icloud email between my ipad mini and iphone 5 on ios 7. it hasnt worked on any of the betas either. i have to check emails on both devices.
 
Yeah I was wondering about this too. Doesn't seem to work for me at all. Any app other than Messages which it worked in iOS 6 anyway.
 
iCloud always synced emails since it was introduced in iOS 6. If I read an iCloud email on my iPad, the notification and badge goes away on my iPhone and vice versa. I wish it did that for Yahoo Mail, but it doesn't.

As far as I can tell notification sync isn't working. None of my app's notifications on my iPhone clear when I clear them on iPad or vice versa. The only ones that do are ones that always did like the Gmail app.
