Mobile Org and idisk.me.com

[ross@rosslaird.info (Ross A. Laird)]

I have carefully followed the instructions in the orgmode manual and on
the Mobile Org site for connecting my org files to my iPod. I am using
idisk.me.com. When I setup the iPod using the instructions on
http://mobileorg.ncogni.to/, I can connect my iPhone to my org files on
idisk.me.com. (I previously put the files there from my Mac). So, the
mobile connection seems to work fine. However, despite many efforts, I
cannot manage to get the staging to work within org itself. The example
given in the org manual:

(setq org-mobile-directory "/scpc:user@remote.host:org/webdav/")

does not manage to connect me to idisk.me.com. I have tried various ways
of specifying the command, my user name, the host, and the directory:

Commands tried: ssh, scp, scpc, ssht -t, http, https

User formats and host formats tried: myusername@idisk.me.com,
idisk.me.com, idisk.me.com/myusername, idisk.me.com.myusername, etc.

Directories tried:
idisk.me.com:/myusername/org/
idisk.me.com:myusername/org/
idisk.me.com/myusername/
idisk.me.com:/org (the directory is there...)

So, not being a programmer, and not being sure how to find out what
exactly is preventing me from connecting, I'm stuck. Does anyone know
the exact format for connecting to idisk.me.com?

Thanks in advance.
