also, we dont know what the directory is to mount from /dev (i.e. on the G1 it was /dev/block/mtdblock3) to get system to mount as rw.
my point in asking is that i'm trying to do something i'm sure a lot of other people would like as well. custom ringtones in /system/media/audio instead of on the SD card. why? because with the ringtones on the SD card, media scanner picks them up every time and lumps them in with the actual music you have on your sd card. ugh.
so, as soon as someone can figure this out, i'd love to know how to do it so I can push the ringtones or cp them using busybox. anyone who can help...well, lets get it going.
