I have a Motorola Photon and I've had it for a few months and about 2 days ago I changed my password to my yahoo email. And it gave me a notification that it wasn't receiving emails because the passwords didn't match. So i went to my email setting and changed the password to the current one and it didn't accept it. So i just took the email completely off of my phone and then went to set it up like new with my email and new password. But it still wont accept it and I have been trying for the past two days.

What should I do?
