I'm part of the Samsung XDA developers forum and do the MCG versions of MIUI for the Samsung Galaxy S.
My Wife asked me to do the same for her Defy phone, so I suppose I have to abide.
So should you wish to flash 1 file rather than 2, and get the added benifits of faster UI, 3D Drivers etc.. Then this is for you.
Install Intructions can be found on XDA just search.
Simply, Wipe Cach and System if you are already on MIUI.
Thanks go out to MIUI Developers, and everyone who has helped in this project.
