I've been finding instructions in other sections of this forums for Google Mail Web-based access, but I haven't found the same for Hotmail users, so I'm posting this.

For those looking for Web-based access to Hotmail using the N810, both:

http://www.hotmail.com
and
http://mobile.live.com/wml

may work for you, depending on what you need to do.

The first gives access to the Windows Live classic mode, which works fine for me.

For my very simple email access needs, I find the lighter-weight second link to be quite sufficient. This also provides Web-based access to Messenger IM (hard to use but OK as an alternative).

P.S. On a PSP, simply going to mobile.live.com does the same thing as the second link. Not so for the N810: browser sniffing appears to be involved.
