JavaCard OS

I am currently working on a project which including the development of javacard 3 connected edition. As I know, javacard 3 connected edition provides much more options - for example web applets. However, I am not familiar with this field. And I can't find any implemention of javacard3 in real life.
Does anybody know the javacard3 implemention in real life?
Which cards supports javacard3 so far? Any ideas?
Thanks in advance for any answer.

If you request when purchasing, they can set at least the A40 and A22 (maybe others, not sure) to use JC3.0.4... and I think the SDK's from Oracle have example applets showing use of those features. The SDK's are free download on the Oracle website.
