I am really really new to this. I am hearing impaired and wanted to download the file that will make my phone louder. I think I have saved the file to my HTC touch but am unsure what to do with it and how to extract it. Can someone guide me? If I dont like the way it sounds, how do I go back to the old one without erasing all of my contacts and info stored on the phone. Thank you very much.
