After releasing Android 4.0 Ice Cream Sandwich source code, developers community working day and night to bring Android 4.0 ICS Custom ROMs for older devices. We have already reported you about successful port on Galaxy S , Galaxy S II and HTC HD2 devices but lots of functions are still not working on released builds. However, some quick updates of builds will soon be available to support all those features which are currently not working in older devices.
