I'm not sure, I think there might be a way to run pure java(which those are btw). Its called research. But anyways, those were for 'feature' phones that had java on them that allowed them to run apps like google maps/mail and opera mini. You are now in the world of the smartphone that has a full OS. If there is some app you can't live without, I'm sure there is an app for it, or better yet, make it yourself and make some money off of it.
