What will the dll and pst do for my phone and how do i install it?
This is more for
advanced user.
Warning! You can "destroy" your U960...
The DLL alone is useless... First you need Samsung PST.
For each model additional DLL file exists.
Example...
Samsung R810 has own DLL file.
Samsung R800 has own DLL
Samsung U960

Each model can be configured by Samsung PST
IF you have the corresponding DLL.
Simplest Feature of Samsung PST is to update Firmware.
For this you need additional
Binary file. At the moment
NOT in public leaked...
You could use Google for study.
