Until a couple of weeks ago I could mark an email unread using a blue link near the top right of the message, in the iPhone email app. It's disappeared recently, for no reason I can work out. Does anyone know what's up, and how to get it back? It's really handy to be able to check a message, work out it's not critical, and mark it unread to deal with when i'm back at my PC.
I'm not on the newly released firmware yet. I'm on a 2G iPod Touch.
