So my mom has a Droid X, she forgot her yahoo password while trying to check on her laptop, so she reset her password. Obviously this meant on her Droid X it said the connection to her yahoo mail account failed. So she went to update her password on the Droid X but it kept failing.
So I tried and it failed, even though the same username/password works on the laptop. I also tried to remove all yahoo accounts and set them up fresh on her phone, still won't work.
