Hi malcolmfromforel,
I agree with you that Americans would have started a class action by now.
So, just in case I didn't make it clear in my posting I have put my complaint in to Apple and I urge everyone with a european iPhone to to do the same:
To everyone else reading here, please give your feedback through the appropriate channel. Numbers will make a difference!

Then, I believe it would be a good idea to post on here a copy of what you sent Apple (as I have done).
That way Apple ignoring its customers on this issue will be online and available for all to see, including
the media.I really wouldn't want it to come down to this but we need to build up a body of evidence to show that this is a matter of concern. Especially if the same is about to happen with low sound output on the iPhone 5S. Numbers make a difference.
