Not showing up for me yet.
When I delete the app, and then go into the AppStore via the phone, I have to re-purchase the app. Button says $9.99.
I get the same error when connecting to yahooConnection failed on all fallback ports
If anyone is having issues logging into your accounts - did you delete your app from the phone or simply update the app? If you just updated delete the app completely from your phone and reinstall it. I'll put money on it that is your issue.
(It happened to me with AIM...)
