@ stephen m - some people have issues with wifi, try to see for youself, I had none. 24.11 has issues with video files playback, 18.11 is ok.
@ mostertruck - try the camera from 4.2 (for ARМ6, posted here) or Camera ICS
@ RZRV8 - it always shows around 420MB for 512MB RAM. The rest are reserved for the system, but are used. Unlocking of RAM is for some models with 256MB RAM, not for you. Use TPT to increase your internal memory (used for installing apps) - you need one with at least 160MB for system to use this ROM.
