In Nokia 7210 document it said if you want to save the java application into Game category, you should state a line "Nokia-MIDlet-Category: Game" in the jad file. I have try it, it works in Nokia 7210 emulator. But when I use the application installer to install the java application, it still save in the Application category. My Nokia 6610 is simply chinese version will it cause the problem. Or use the Application installer to install application should have another way.
