I know this has been posted before, but I am unable to find a solution. I have my Blackberry set to access my email, but I have unread email on my blackberry when I have already read the emails on my desktop applicaiton. How can I make it so that if I read an email on the desktop, it shows up as read on the blackberry?
You can't with BIS+Gmail IMAP. Currently it's one-way read/unread sync only. You'll have to wait for RIM/Google to implement full two way IMAP syncing. Or you can use the Gmail app.
