It's JB 4.1
There is a very useful compilation of stock and custom rom links and many more, thanxs to xminirom, the author :
First of all, you should read a little more. Make sure to not break the device.
It's very important read carefully the ROM installation's instructions before doing nothing.

There are various leaks, but nothing for sure. Who knows...
