It looks like Zumobi is going to be be blessing for mobile content developers. I just talked to Beth Goza who said that using the Zumobi Tutorial, she was able to develop a Zumobi tile that uses her own blog's XML feed. The fact that their service will take everything from an XML feed and render it for the device will save developers tons of time and money.
"In general, developers are excited that we created a new platform that they don't have to develop differently for different types of handsets," said Goza.
The beta version of Zumobi for Windows mobile phones is now available, Java, and iPhone versions will be available in 2008.
