Yahoo! Japan for the iPhone

So, Yahoo! Japan website came out with an iPhone edition. Not sure why they didn't announce it before the iPhone launch, but it is available now. This may be good for Japanese speaking iPhone users in other countries too as there were hardly any contents in Japanese intended to be accessed by this mobile phone.

The URL (website address) is not described on their website. I guess they expect you to access http://yahoo.co.jp/ from your iPhone or maybe there is a preset on the Japanese edition. If you want to try it from your Safari browser, go to http://ipn.yahoo.co.jp/.

Mail Setting on iPhone (Yahoo! Mail sucks...)

What's up with Yahoo! Mail? Apple said that they partnered with Yahoo! and developed push mail for the iPhone but I can't even set it up...

I had an existing account on Yahoo! so I tried to use that. In the mail account settings, I select Y! MAIL and entered my email address and password. But all I get is:
Cannot Get Mail - The user name or password for "imap.apple.mail.yahoo.com" is incorrect.

So I thought, maybe my bad, I jumped on it without reading instructions, let me go to Yahoo!'s website... And what do you notice? Yahoo! has no information regarding to the iPhone. What! I don't understand. Yahoo! and Apple worked together on this piece which is supposed to be one of the main feature and no documentation?

Well, I was already very disappointed, but I didn't want to give up that easily. I did more research and found this article on Apple's website:
iPhone can't access Yahoo! Mail when non-alphanumeric characters are used in the account password
It mentioned about the same error message that I was getting, but unfortunately it was no help. I changed the password. I even created a new Yahoo! account, but nothing lead me to success.

So again, is this issue related to not having an account setup with AT&T? Whatever the reason is, lack of documentation is an issue with the iPhone. I would like to rename the iPhone to "mPhone, the mystery phone."

But the good news is, I had no problem accessing Yahoo! Mail on Safari, the last resort for all applications on the iPhone. And even better, I don't use Yahoo! Mail.
