Slim ICS, as don't see much need for all the extra stuff apart from eye tracking to keep the screen on, S-Voice functionality goes in one ear and out the other, NFC not for me, Social tagging can leave me alone, shame the screen is sub standard to the SGS2.
Still loving my SGS 1 but am due an upgrade so may as well get this, hopefully the GPS is not as ****e as the SGS is. ended up buying an iPhone 3GS just to use with TomTom.
Now if you could give me TomTom on the SGS3 then you'd be talking.
