Since upgrade, every time I click on Get Mail on my computer, I get the message The POP3 mail server (inbound.att.net) does not support UIDL or XTND XLST, which are required to implement the ``Leave on Server, ``Maximum Message Size or ``Fetch Headers Only options. To download your mail, turn off these options in the Server Settings for your mail server in the Account Settings window. So, I turn those settings off, and now I can't see my new e-mails on my phone. When I first turned those settings off, I got 80 duplicate messages on my computer that I had already seen. But when I look at my phone, my inbox is empty, and I can't download new e-mails.

That is how POP works. It downloads messages and removes them from the server. Unless you use the option to leave on the server which your provider no longer supports. IMAP protocol is more suited when you want to view messages from multiple devices.
