From the JPhone dept.:
Sun Microsystems is developing a Java Virtual Machine for Apple's iPhone and plans to release the JVM some time after June, enabling Java applications to run on the popular mobile device.

The JVM is to be based on the Java Micro Edition (ME) version of Java, said Eric Klein, vice president of Java marketing at Sun, on Friday afternoon. Apple had not shown interest in enabling Java to run on the iPhone, but Sun plans to step in and do the job itself after having pondered Thursday's release of an SDK for the iPhone by Apple.

"Now, the iPhone is open" as a target platform, Klein said. The free JVM would be made available via Apple's AppStore marketplace for third-party applications.
