I have noticed slowly, that the difference in time between a thread response and the email is fairly significant, and the last few days, it has taken up to an hour for the notification to come through. I don't know why, but it used to be about 5 minutes behind, or less. But for the last day or two, an hour. I can't depend on it to update me. I check my email on an iPod Touch 2G, and always check the timestamp, not delivery time. It is about an hour behind. Arn?
