First of all less of the CAPS, it's irritating ;P
From the Firmware info you have given I do not recognise it or the codes. are you based in India? If so, to be honest you may have more luck on XDA forums as they have a larger member base.
You could check what the latest firmware for your model phone is at SamMobile.com.
If it's the Galaxy S from a couple of years back then you may want a custom rom.
