I also use YOOMaps and was able to get it to work. Here is a quick explanation:
I'm assuming you are using {loadposition yoomaps} for your article call for the map you want displayed.
Goto Module Manager and make a copy of you yoomap module
Edit the module copy and call it YOOMap Mobile
Change the position from yoomaps to myoomaps
Change the dimensions of the YOOMap from what you have for DESKTOPS to a width of about 180 for MOBILE devices
Enable the module
Save the new module
Goto the article manage and make a copy of the article that you call the map from. Edit the copy and make the name the same as the original article, but change the loadposition from yoomaps to myoomaps.
Save the new article
Goto Menus>mobilemenu (or whatever you named your mobile menu)
Edit the menu item that calls the article containing the map
change it from the DESKTOP article to the new mobile article you created (above).
Save the menuitem.
Check it on your phone.
This will work, but you will then have the change the menus for imode, pda, and wap as well.
