since you insist with this, yes, the rw permissions were allright. in all the right places. and the folder was where it should have been. it's just that i'm no expert with installing igo. nor with android for that matter. i'm just an *amybe above average user, who couldn't install it. because of the way android names the external card. even if one program can "see" it as /sdcard2 and /storage/ext_sd and a few more, apparently igo doesn't. because... who knows why. actually, because "linux". and that's the reason it will never replace other operating systems for the average user.
and then i decided i should try all of the damn symlinks. that's all
thanks
