I set up a gmail account on my NOOK color. It downloaded a lot of messages, and I only wanted to see new messages, so I deleted the messages. THen I found that it had deleted them FROM THE GMAIL SERVER, not just on the NOOK itself!!!!!!! Can I undelete them? They appear in the Nook email trash but NOT on the Gmail server Trash! I don't see how to undelete them.
It turned out that the deleted emails eventually DID show up in the Trash folder on the Gmail server, although they had the label lmap/Trash. It would be nice if the Nook worked like my cell phone -- only retrieves UNREAD messages, and when you delete them, it asks if you want to delete from the phone only or from the phone and the server.
