Still no joy on mine. Both accounts have recent messages when I log in from a computer. Only one account shoes messages on the phone. This is using IMAP not POP3. No need for a vid. LOL. It's not like mail settings are that hard to configure.
Did you have to remove the HTC to get any of the accounts to work? The first account I configured actually works just fine with the HTC in there. I have tried it both ways on both accounts. Same result either way.
What release are you on?
