Cross-Browser Colour Management for PNGs

I apologise in advance if SO is not the place for this. This seemed the most appropriate Stack Exchange, but still not ideal...

Anyway, I have a number of PNG images on a website I'm developing. They look great in Firefox and IE, but when I check on my iPhone, the colours are all wrong (sometimes dramatically). After a bit of Googling, I found that the problem is due to colour management in Safari and my PNGs using some other profile.

I'm using the GIMP to make my images and I found this blog post about how to fix it. However, I tried this and it had no effect. The thing is, I don't seem to have any ICC profiles installed on my machine, so I downloaded the ones I found here; but still no luck... I also found this link in SO's search side panel as I've been writing; but removing the gamma correction when I save the PNG doesn't do the job, either.

Can anyone point me in the right direction, to get my images to look right everywhere?

So likely your browser treats CSS colors as described in http://hsivonen.iki.fi/png-gamma/ which, of course, does not match up. Instead of inserting sRGB you can also remove the whole gAMA chuck or embedded profile, which may increase your odds by a tiny bit.
