Unhappy [Q] Is there any Custom ROM for Karbonn A4? and how to install it?

Hi,
I have Karbonn A4 rooted it runs on 2.3.6 (ginger bread OS). I'm pissed off with its internal low memory of 127 MB, i tried using Link2sd, all apps are saved in SD card, but still i have 102 MB used in internal memory. There is no way of swapping internal memory with SDcard?

I need custom rom for my divice, like jelly bean 4.X.X.
Please anybody can help??? i will be very thankful.
Regards,
Sam
