More info bout technical matters :

You must bear in mind that new phone from Samsung and LG offer 3 layers memory for phone which is internal memory, internal SD (/mnt/sdcard) and external SD (/mnt/sdcard/external_sd).
where other or old phone have 2 layers which is internal memory and external SD (/mnt/sdcard).

when download gameloft games, data file is save at default directory ( /mnt/sdcard/),
it is save to external sd card for 2 layers memory phone but comes to 3 layers phones (SGS,SGS2 and SGW),
it save to internal sd, so only 2GB can use for games. ( For us the SGW users)

must root to use 3rd party apps to mount , or swap your memory (internal sd and external sd), or patch ur games apk file (change the default data directory save to mnt/sdcard/external_sd) only can move data files to external sd in SGW, bear in mind.
