How can I wirelessly Sync my Yahoo Calendar to my iPhone?

I have had exactly the same problem! I have done all you did above; have read all the yahoo articles on syncing and how to restart a sync; I have deleted and readded yahoo mail; I have reset the phone to settings; and have been in to the apple store where the firmware of the phone was reset and updated to ensure the problem wasnt with the phone. I run my business from my phone so calendar is non-negotiable.

Yahoo are impossible to contact - I have had the same loop as you have described and am sooooo frustrated! Can anyone advise please?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
