i tried to install Real GTA3 Final mod (search it on google because i can't post links yet -_-) to the mobile version of GTA III and it works ! . just tell the wizzard to install te mod in x:\Android\data\com.rockstar.gta3\files\GTA3 (sd-card) and it will work

BUT ONE THING I NOTICED FOR NOW: THE RIMS FROM CARS DOESNT SEEM TO WORK !!! they are either invissible or too big xD
