I have had my account connected to the phone through the email app (pre-installed) since I got it in August without an issue. I had to change my email password this morning now no matter what I do I can't get it to work. I keep getting a message saying error 503 service unavailable. I checked if I needed a software update that is good pulled the battery and even tried deleting the yahoo account and even when I try to do that I get an error saying delete account failed. Any other idea's?
