Java ME testing has gotten much simpler and more robust with the announcement that UTI has become an independent organization with new support of "Simple App" testing for Java ME mobile apps.

Java Verified Simple App Testing
Here's a quote: UTI announced that the organization had become an independent body... UTI officials launched support for "Simple App" testing services. UTI said Java ME is the most broadly deployed mobile run-time?it is used by nine of the top 10 handset manufacturers and powers nearly 3 billion phones in more than 150 countries worldwide. Wow! That's 3,000,000,000 phones in 150 countries. Nice! Java ME is still the clear leader and is king of the mobile industry. Or in other words, Java ME rules while iPhone 4 drools (with its bad antenna problems). :-) I kinda like it.
