When it becomes difficult to support a certain platform, one option is to provide a separate website that is written in simple HTML, and redirect that platform to this website.
One problem however is touch-based interfaces. When we render the iMode site on a touch device like an Android smartphone, the links are too small to tap with a finger. Although even the most incapable Android smartphones are able to correctly render the iMode website, the links are un-tappable because they are too small. One solution is of course to have the user zoom-in and out of the window. This is however a pain on old Android devices, because zooming is not smooth and in some cases, you do not have pinch-to-zoom.
We are currently investigating if we need to redirect some old Android devices to the iMode website, and if necessary, whether we can customize the font-size, etc. so that this site is usable with a touch interface.
