When I first got my Moment, I couldn't get my Yahoo email to work under the "email" app. I tried the following settings and it miraculously worked! I've been getting my Yahoo email on my Moment flawlessly for the past month: Go to manual setup > IMAP account and change to these settings.... INCOMING Imap server - imap.mail.yahoo.com port - 143 security type - TLS (if available) OUTGOING SMTP Server- smtp.mobile.mail.yahoo.com port - 25 security type - TLS (if available) * check Require sign-in However, my Yahoo email just stopped working on my Moment yesterday (it won't load new emails into my inbox on my phone)! It keeps telling me "username or password incorrect".. WTH!!?? Is anyone else having this issue recently? Could this be a new change that Yahoo made? Does anyone else have any ideas of what the next step could be to resolve this? I'll bet my turkey that if I called Sprint Tech Support they would refer me to Yahoo, and if I called Yahoo, they'd refer me to Sprint!! Can anyone help? Much appreciated.. Also, if you are using the same settings that I've been using and it is still working okay for you, please be so kind as to advise- so I know that that setting above is still working, and it is more likely just an issue with my Sprint Account. Thanks.
