or password, I have not changed my password or account information. Why I can not access my email? " I access my email accounts on my pc so that the fault lies with my iPhone (Ok everthing works in other areas of the phone) came into the menu to change my password to see if someone has changed the information, even though my phone always with me and I alone know, I know, having said that, if I can access and update my email even if the page is open on my phone, right is that it must be the same on my pc, deny me access to my Yahoo email account … The only conclusion I can draw is that recently changed my SIM card solve a problem with my mailbox, it does not work and was advised to do to activate my voice mail, but this should not affect my open my email account.

Sorry no solution, just wanted to say that I was the same problem since 09 am ET in the UK too, which really bothers me !!!!! Hurry please type Yahoo!
