I am in the USA and I am having the same issue today with my iphone and my yahoomail account. I have tried the same things as you. I went to the yahoo website and emailed myself a link to download yahoomail to my phone and I made a separate icon for it.
It works OK, but it's not in the mail section of my phone, it's a separate spot. I will try to add my yahoo account back in tomorrow, but I am thinking there is some kind of issue with Yahoo and my iphone software right now. Good luck!
Sorry, I can't help. I would've recommended not getting IO6. IO5 was better.
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.
