Here's a good one after Froyo install... All of my email accounts now sync from the server side. In other words, if I download my email to Outlook, it deletes it from the server. When the phone downloads it from the server it leaves a copy on the server.. I do this so I can keep it all in Outlook when I am on the computer.. Just downloaded it with Outlook and when I went to delete it off the phone like I have always done, my email account sync'ed and the emails were gone.. Nice.. Now I don't have to take the extra step of deleting all email off the phone..
