How much flashmemory does ICS with touchwiz need and how much does the SGS have?
Upgraded from 3.1 to 3.2 through CWM.

Nice kernal! Testing on 1.4ghz with pimp my cpu on 1450mV did a few minutes stable in "stress cpu". Also finished a few races in NFS. Tried 1.44ghz but that locked up fairly early in race. Probably need more volts, not sure if that is "safe".
