[1.1.1] Low Audio volume ? Try this. It's better than iVolume.
Compatible with all firmware versions.
Modified by me. It's better than iVolume. I feel very uncomfortable while using iVolume. It's simply too loud. It's loud enough to break your ear drums when you use earbuds. So I modified the original plist files using TextWrangler and saved it in the original binary encoding.
Download and unpack
Put com.apple.celestial.plist file in /var/root/Library/Preferences/
Put SystemSoundMaximumVolume.plist file in /System/Library/Frameworks/Celestial.framework/
Restart the phone to apply the changes.
I just took a peek at the 1.1.2 files. They seem to have the same structure as 1.1.1. Therefore my files should work on 1.1.2.
