forgot to say it works on the motarolla V8 and LG KF800

hey i have made a game on midp 2.0 and CLDC 1.1.  I have a samsung tocco and try to load it on my phone but it doesn't work, it comes up with unsupported aplication, also it doesn't work on my other flatmates samsung soul.  I tried it on my flatmates  motarolla V8 and my girlfriends LG KF800.  Does anyone know if i need to do something or is it jst samsung phones?

Thanks
