My yahoo email has quit working since fri jan 2. I can't send or receive emails or see ones in my folders using iPhone email app. I can see all emails if I use yahoo app. It's frustrating when others in my family don't have issues. Just me. I'm not a newbie as I've had iPhones since the 3G. I have reset and deleted my email account several zillion times. Anyone else have issues? This is ridiculous.
