The phone has a 16 GB internal SD card. You have 2 GB of space inside the internal SD card to install apps - meaning up to 400 t0 500 apps !!! If you are installing games, dictionary, etc - the additional data/downloads portion will be downloaded to the other 14 GB portion of the internal SD card

Why would you want to install these on the external SD card - which by so doing will only reduce access performance on the phone ??

I think you got a wrong info here.

Since Froyo, the ability to install app into sd card is there. Root is required for Eclair (2.1 and below).

Now, back to SGS. Since SGS1, the phone has 2GB space just to install apps. And some apps especially games are smart enough for not clogging all the space with their data. It will move additional data (music, video, textures etc.) needed for the game to next available storage mount which is sd card.

Phone which are limited ROM (for most midrange phone and last year flagship model) which only has 512MB ROM (availability is less than that) requires this functionality.

Most phone in the market has 512MB / 1GB + external sd card. SGS has 2GB + 11GB internal + external (depends on the sd card size).

IMHO, all SGS owners (SGS 1 and 2) did not even bother about move to sd card feature.

Hint: If you look on the first page of both official SGS1 and SGS2 threads. There is no info about this functions, so not needed 

if u mean adhoc.. i believe we have the same problem.. we need to have wpa_suppliment to be modified.. waiting for xda dev to do one for us
