someone's working on it???
it would be awesome!
it brings a lot of fixes!!
Or you can use nova, it's pretty smooth too. I use eXistenZ v1, I find absolutely no lag. Yet I've done some editing to my build.prop for smoothness by following this thread http://forum.xda-developers.com/showthread.php?t=2376536 ...
No its not firmware dude.. That's your model phone..
Take a look at your build number.. Be sure you have the latest one (.423)
If it still lag, man.. I suggest you to install Honami's home, it's smooth like your phone running Gingerbread..
knock knock where's Nottach :D
something really big might being produced....do not disturb lol
