its probably miui patchrom, which is a miui official porting method i guess you could say, it ports miui from a stock gb rom, i was actually thinking of doing this when i got hold of a working atrix 2 again. Its basically turns a stock rom (2.3.6 motoblur) into a miui rom, you cant really tell it was based on a stock rom, but they are usually just as stable as stock, all features working.
Bpear I downloaded this, the ATT, and restored. Had fc's for messaging and settings. Kept hard rebooting as well. Otherwise looked like something i wouldn't mind trying as long as it was ported a little better.
