I have always been able to set up my Pre to get pop email from my Verizon.net (Fios Email) via my Yahoo portal.

BUT it never worked since they added the Yahoo synergy connector.
I would do a manual Yahoo client set up on the Pre and use my vz login info.
the pre would sync then in 20 min no more email and id get the dreaded password incorrect issue. ( password was of course correct )

i tried a few times but it just didn't work....so i left it on the pre just dormant figured it was a Fios / Yahoo thing since my address was not @yahoo.com it wouldn't work via the palm.imap.yahoo settings.

Well the other day it started working and has been working since.

So anyone with those SBC Yahoo accounts or other Nonstandard Yahoo accounts will be working better now.
