Well, not really having checked out it physically and giving a review is not right, but the specs look very great on the paper, be it the 2 GB or 4 GB RAM model. Only on usage the real pros and cons could be arrived at and until then based on the specs.
I find it really gud phone worth buying @ 13K for 2 GB and 16K for 4 GB model. Lets wait a few days to really find out at what price they are offered and also wait someone to give a hands on review.
