Non game applications
We produce an application aimed at changing the way people think of using mobile java.

However, due to the lack of proper testing by some Korean manufacturers. Our application cannot be used on some, allegedly, MIDP2 devices.
Commonly encountered problems
platformRequest does not work. This is usually due to some arcane configuration issue, like separate gprs settings or security setting being unchangable by the user.
Another less severe problem for my application arises when camera access is either not available, or the camera implementation is too poor to be useful.
