MyMaps for Mobile
Have you ever spent hours creating a wonderful MyMap and then wished you could view it on your mobile phone? Well now you can thanks to this web-app that allows people to view their My Maps on their iPhone or Nokia N95.
For support in using the application there is a Google Group called MyMap for Mobile where it is possible to ask questions about the application and talk about how it works.
If you are looking for some great MyMaps to view on your mobile phone (or even on your computer) then check out the Google MyMaps Directory.
