This is a port of Manup456's Galaxy theme for the Miui ROM. This is a them only file so do not wipe before installing. I highly suggest you don't install this until you have your Miui ROM under control and working first. This theme includes fixes for the market (build.prop), the stock Miui SMS app, and the Account syncs fix.

This is beta 2. Changes since the last beta I released include updated notification icons, fixed notification font colors, Galaxy-esque system icons, and Galaxy S widget backgrounds for the Power Control and GenieWidget.
