Mobile GMaps has just launched. It’s a free piece of software that displays Google Maps and Keyhole satellite imagery on Java J2ME-enabled mobile phones and PDAs. (Mobile GMaps is being released by an independent, and is not an official Google product)
The application is being distributed under a Creative Commons Attribution/Non Commercial/NoDerivatives Licence. You can download, use and distribute the application free of charge for non-commercial purposes.
Sadly it doesn’t currently allow you to give it an XML file of co-ordinates in the same way the “Real” Google Maps does. Hopefully the author will offer this functionality soon, potentially making it a really valuable remixer’s tool.
