Sure.
Use the UCLL6 plus root package from the link. The one-click downloader is easiest. Then, if you want, install Mobile Odin lite or Mobile Odin pro and use it to flash a custom kernel such as AJK or Siyah.
And... I would suggest you read through the first link in my signature to learn the basics.
Dude I just updated to official ics 4.0.4 and flashed kernel siyah 4,the problem I am facing is scroll lag maybe the screen has became less responsive after update,it also lags while typing...what do u think this problem is bcz of kernel or rom?
