I bought this mobile two year back. It was a good mobile. There is no hanging problem at all. It has 512 mb RAM. It cost me nearly 7200 for me. Battery packup is good. It also looks well in its design. Its value for money. It sounds speaker was good. It was a 3g mobile.
It supports only 3g and its a dual sim mobile. It can be expandable upto 32 gb.
