No its not rooted. But as someone pointed out earlier, rooting your device doesn't really make any difference. I know launcher pro is smooth but I always liked ADW the best. I haven't tried using the EX version though. Go launcher is just OK. Maybe I should flash cyanogenmod on it or 2 year old Galaxy 5 is running ADW fine and it has much more Widgets. But its running CM7 though.
