Yahoo Mail not working!

Hi there,

Since last Monday (25th August) my Yahoo Mail has stopped working. It used to push e-mails to my phone no problem but it won't anymore. I have tried deleting the account and re-entering the details - bizarrely this re-downloads the e-mails in my account but only up until Monday 25th August.

Has anyone else experienced this? I figure that 5 days should be plenty of time for Yahoo to sort it out if it is a server issue. My Gmail is still working fine.

Thanks!
