FAQ #9 talks about internal memory. My question was about external memory (SD card)..

16GB is total raw, after formatted to any filesystem, you won't get the full 16GB
Why on earth you wanted to move the app into sdcard? You have 2GB space for apps, plenty of space there. Furthermore, the internal sd is unique to Samsung since SGS1 which other phone will treat it as external sd (microsd).
Most other android phone will see the memory like.... internal rom (from 256MB to 1GB) for app -> external SD (memory card from 2GB to 32GB)
For SGS it will be like... internal ROM 2GB for app -> internal SD (MoviNAND / USB Storage) 12GB -> external SD (memory card from 2GB to 32GB)
In conclusion, "move app to sd" for other phone is the external SD; but for SGS, it is the internal SD.
