It is a Samsung Galaxy S3 if you are not an HTC One X user and Apple 5 has its own limitations.
Samsung would be coming up with really good innovations this year and as we are hoping for a really expensive and high end mobile with a dual sim too, right now the most expensive dual sim is Samsung galaxy grand duos only for 28000 or HTC desire SV, hope they launch a samsung galaxy s4 or s5 with a dual sim version too whatever the price be even if more tha 50K :)
