Depends on the features of your MIDlets. The only way to know for sure is to test. One that won't work consistently is CustomItems that depend on the direction keys for navigation. All touch screen devices aren't the same either. Some have direction (arrow) keys and a Fire key, others don't.
There are no new questions, but there may be new answers.

One more question: I don't think J2ME provides APIs for touch screen programming... I don't think there is any way of listening to touch screen events etc. Am I right?
