Nov 23rd 2013 - MIUIv5 PatchRom -
MIUI version: 02.20131123.062601 (It's patch, the versions are date compiled)
It is similar in nature to a port and does not violate any of the laws of this forum.
I am a member of the official porting team so there can be no question about wither I have the ok to put this here or not even though MIUI for the SII is in beta.
