This phone has come in the market in Feb 2012. just now (last week) I have bought this phone. So far the experience is good..It has all the features I wanted..and imp thing - all the features are there in my budget (Rs. 5400). If you buy this phone from flipcart.com, may be u can get 8 GB free memory card (special offer) with the phone (i saw on the flipcart’s website) but I am not sure about the service and the product of that as I have not experienced it.
You can read this phone’s full features and specification here:

Camera quality is specially good (even on night mode :))
Many apps (games, s/w) u can download and enjoy them.
Dual sim (my need)
I found it little bit slow, when I call or disconnect the call. Its good though..
