Hi ,
I am a newbie and hobbiest learner to mobile games ..I have developped some 2d games using J2ME MIDP 2.0 API . I want to start making 3d games for mobiles.I have heard that java is slow...so is javax.microedition.m3g good for making 3d stuff ??Do they give good performance over actual mobiles ?
......I want to learn this thing to a good level so that I could take it up as profession.... I am highly confused what should I learn....C++ to develop for Symbian OS using Opengl_els(I don't remember the name correctly) or I should continue java and start exploring m3g package?

and please tell me some resources ,good links to start making 3d games for mobiles.

Thanks
