I have been a user of Verizon Yahoo for many, many years.
I have recently (about 4 months ago) got an iPhone 4 and have been successfully syncing my contacts between my Verizon Yahoo account and my iPhone (running iOS 5.0.1). Suddenly, on the afternoon of November 14th, my contacts would no longer sync and all of the contacts were removed from my iPhone (luckily they are still in Verizon Yahoo). I've tried deleting the account from my phone and setting it up again, but no luck). I send/receive email without any problems. Can anybody help?
