JavaCard 3 in real world?

_x000D_ _x000D_ I'm currently working on my diploma work. Part of the work includes development of JavaCard applet for regular SIM cards. First option is to use JavaCard2.X API and use APDU commands to communicate with the applet. This might be very tricky as I need to develop client-app for android (which will be communicate with this applet) and that is so far possible only trough special - not so user friendly - API called Seek-for-android. (if I'm wrong, please correct me) However, I also came across JavaCard3 Connected Edition, which provides much more options - for example web applets. Using webapps, deployed on SIM card and accessing them through browser in mobile device would be very convenient (of course developing such applet would be much easier as well). Problem is, that I can't find any mentions of Javacard3 being used in real life, or even on real SIM cards. I can't even find any mentions of possible date of release of such cards. Actually, there is almost no information on this topic. So, my question is - do you know anything useful about this platform? Anything about real-life usage? Which card supports Javacard3? Are there any developers smart-cards, which are "JC3 enabled"? Will there be SIM cards with this platform in the future? Thanks a lot for answers!!!
