How to set the Email(i) address that you get with your iPhone 3G in Japan?

Question

This isn't covered in the U.S. manual probably because the feature is slightly different in Japan.
Basically the issue is this - cell phones in Japan have their own "cell phone email address". I believe that's not the case in the U.S.
So when I got my iPhone 3G in Japan today from Softbank, the cell phone provider, I also got a new email address [email protected] The "i" stands for iPhone.
The question is what to do with it? Unlike other cell phone providers, this is not set up on the cell phone itself when you get it.
Thanks,

Answer 1

I figured it out.
With the iPhone you can set up multiple regular Internet email accounts directly in the Mail app, using either IMAP or POP3 and even have your existing accounts synched from your computer.
It turns out that the [email protected] email account you get with your iPhone is just another "Other" account that you set up in the mail settings. When you add your Softbank address and password it automatically sets up the server to be IMAP for checking mail and the correct SMTP server and it just appears as one more push account in your accounts list.
I'm not sure it is really useful for anything or not, but since a lot of people want to know "what is your cell phone address" I guess it is best to set it and have one rather than explain why you don't really need a separate cell phone address for your iPhone.
It's sort of interesting. And it is actually an improvement over traditional Japanese cell phone email I think. And you can see nice HTML mail to boot.
Anyway, I hope this helps anybody else who doesn't know what to do with their extra Softbank address that comes with their iPhone 3G.
