Is there is a feature for the Droid that shows if a text message you sent has been open/read? I have the delivery report, but that only shows if it was sent to the phone, but I want to see if the message has been opened yet. I know my old Voyager had this feature. If you went to your sent messages it would show an arrow if it was sent and then a check mark if it was read. So far I haven't found anything like this on the Droid. Even if it was an app would be nice.. Does Handcent SMS have this?
