There seems to be an issue with accessing Yahoo when you're connected via WiFi versus over the Sprint network. Yahoo seems to be wanting to avoid you accessing your pop mail if you don't have one of their paid accounts (which is cr*p if you ask me since there are an abundance of free alternative email services out there... think like what happened when AOL pulled this too).

What's really weird is that I had Yahoo mail on my BB before I got a Hero and there were no issues at all. Only when I got the Hero and hooked up to the WiFi. When I turn off WiFi, it works again - only after a little while though.
