Confirmed to work. I did run into one problem though. The apk attached in the OP unpacked update.zip to the memory card, but for some reason the recovery image was not able to recognize update.zip file. All I did was make a copy of update.zip to the root of the internal memory and everything worked perfectly. Superuser will installed as well.
