abb...no worries, we will have you techno-savvy in no time. That post your refering to is a zip file containing a reg setting/file, all you need to do is to download the file, un-zip the reg file and place it anywhere on your device (main memory, My Memory, or even a storage card) and then just click on it. The setting will automatically make the change it needs to on your device and you have nothing more to do than enjoy the change made by the file!!!
Hope that helps!!!
