Hi, is there any way to increase the microphone recording level on my jailbroken 3GS? An app maybe?

Quite a lot of folks complain they cannot hear me properly ever since I got my iphone.

I was able to find this section in /var/mobile/Library/Preferences/com.apple.celestial.plist:

Code:

<key>SpeakerAndMicrophone</key>
		<dict>
			<key>Audio/Video</key>
			<real>0.6875</real>
			<key>PhoneCall</key>
			<real>0.8125</real>
			<key>VoiceCommand</key>
			<real>0.875</real>
		</dict>

But I am afraid to change the 0.8125 to anything esle..

should i make the same or what ?
