MIUIV5 based on Sony sources
thought i'd share with you.
From what i can tell is that it's running on .350 (4.1.2) and that it's for both locked and unlocked bootloader (correct me if i'm wrong).
However, my chinese is non existent (;P) and google translate just spews out random gibberish. Therefore i can't provide more information or any links as i don't have an account.
If anyone here knows chinese then please provide more infos on this, and maybe a link to the rom.
