After Analysing for one month, Finally I had bought SAMSUNG STAR S5233. Mobile is mind blowing and in the range of 9000 Rs/. Camera 3 megapix, Smile detection, Sensitive touch screen, three desktops, folder lock, photo calls, Blasting Sounds and nice looking player, Accelrometer for sliding and rotating, Mobile Tracker, Personal Widgets where you can customise your desktop and etc..
Finally the battery backup for me it is lasted upto 3 days. If you use mp3 for 2 hours a day, 1 hour on calls and 1 hour on other usage, then this mobile battery will last you atleast 2 days solid. Everything is there except 3G and Wifi and flash(make difference in night pictures, but under light it is too good). But for this price, features are more than enough. You can blindly go and purchase one. This review I thought of righting on 1st day of mobile purchase, then I decided I should use it atleast 15 days, then I should write....Now I done it..
