I got this device from less than a week and so far I tried 3 roms
-Stock ROM with latest update 4.0.4
-SVHD 2.1 (It's really amazing to be a ROM based on Sense)
-MIUI v5 3.11.29 (Just Installed and testing).
So far I prefer MIUI because I always loved it, but SVHD is a really good ROM, now gotta check out about what you guys are talking about :3
Some link may be useful.
