Just got my new phone yesterday. I added my two email accounts through Yahoo. Everything was fine, but I recently noticed that my email in one account isn't being pushed through. My phone says 'Unable to connect to server", and the name of my yahoo account. I'm not sure if I'm having the same issue with my other account as I don't receive emails often. I have a Wi-Fi signal, and everything else seems to be fine with the phone. Any ideas or suggestions? I have a Samsung Galaxy 2S.
