I don't have the option either. Can't tell what device you have while I am on wap. I have tmobile never heard of it. Recon means it syns with your mail server and updautes you read emails provided your set up for IMAP

Example... you may have deleted something on your 8900 which didn't take into effect on your mail server. Reconcile should help it get deleted their as well.
I want to know if its possible for my emails NOT to be shown in my messages inbox? Its getting annoying because it shows in my text box and the email box at the same time.
