how do i install drivers???

You have to flash the phone to use new drivers. To flash you need to have some tools like XS++ and FAR manager. Using FAR manager you can enter the phone. then you can find the path as said above.
You wont be able to see those generally when you connect your phone to computer. Search "how to flash?"

can any one tell em how to do it using xs++

Look here:

I like setool 2 lt for installing drivers and such..

If you cannot copy original drivers from the phone, then you search them using Google and download it.
