Boosting your iPhone speaker volume
After finding the maximum speaker phone volume too low for normal use, I decided to poke around and see if there was something I could do about it. I knew that the Celestial framework folder (/System/Library/Frameworks/Celestial.framework/) had a Maximum Volume property list, so I decided to edit mine and see if I could effect a volume boost.
In the property list, I adjusted the Default -> Default value up to 0.99, up from 0.7 and found that it seemed to nicely boost my speaker volume. Is this a real fix? Or did I just psychosomatically convinced my ears that they were happier? You tell me in the comments.

Could a similar trick be used to lower the minimum volume? (I find the iPod touch minimum volume just a tad loud when used with my Shures).

I'm really surprised, Apple neglected that Minimum volume issue and did not do anything about that.
Looks like I have to by a different earphone with inline volume control.
That is really sucks.

Is there a variant of this to raise the maximum volume of a macbook/macbook pro ?

in Quicktime Player you can raise the volume over the apparent maximum by holding shift while pressing the up arrow. Or you can press CMD-J to open movie properties, click on the sound track, then go to the audio settings tab where you can set a 6db boost.

You can use Plutil command line, but not sure how to set the Default->Default value. Erica little help here on the syntax of this?

An app would be great. My volume is horrible. My roommate's iPhone has twice the volume mine has - no idea why.

Just changed the SystemSoundMaximumVolume.plist but couldn't hear any difference…
I'd really like to boost the iP speaker.

Peter: I tried it, and I didn't notice a difference either. I even restarted the iPhone to make sure.
Oh well!

You need Erica Utilities as well, it contains Plutil.
The command for setting it to 0.9 will be something like:
plutil -i DefaultDefault -v 0.9 /System/Library/Frameworks/Celestial.framework/SystemSoundMaximumVolume.plist
But the part I have after -i is NOT CORRECT, so don't use it. I am not sure how she handles sub-items in plutil, because I can't find anything on it yet.

You can open and edit the .plist by using the trial of PlistEdit Pro from FatCat Software.

This worked without a doubt on my 1.1.2 modded phone. I use the phone as an alarm clock every day and am WELL acquainted with the previous max volume's limitations.
