Check the Samsung Galaxy pocket, which has all features you mentioned in the list. I bought the phone at Rs.6500 last month and heard the rates slashed to less than 6k.it has a good battery back up and works well,even i connected to net all time and using some additional applications too.
Hey friends, Thanks for sharing the info. As of now I have to slow down on getting a new phone for various reason. Kidos next educational year starts, Son going into 11th so might change school and lot of other things.
