Dear LMF, I am not sure if you are aware, but you are replying to a thread that was last responded to in January of 2011, 4 years ago last Monday. In fact, of all the members who participated in this thread, only one has been active here in the past year.
If you are having trouble with your phone such that you can't get to a comfortable volume level, between being too loud and too soft, unfortunately you may be faced with moving to a different phone model. These are digital devices, and usually the volume incremental changes are a product of limitations built into the hardware chips that amplify the audio for the speakers.
In other words, there may be perhaps 10 or 15 incremental volume levels, and each one may be a certain percentage higher or lower than the previous or next, but there may be no way to change any one increment to obtain a smaller change in the perceived volume.
I do know of apps that can "amplify" the volume by a certain amount, so that phones which are not loud enough can be made louder, but not all phones work with all apps, and some phones can not work with any. It is possible that you could combine a volume "booster" and go with a lower volume setting to accomplish a "in-between" volume level. I would suggest you exercise extreme care given your situation if you choose to experiment in this way. You could potentially cause even greater discomfort if you were to accidentally increase the volume significantly and be unaware until it's too late.
Thank you.
