You're more then welcome to be the first one to try flashing experimental roms on your new xoom if you want, that way you can be first to tell us which method works for australian xooms.your "informative" post is just a rehash of http://forum.xda-developers.com/showthread.php?t=1089695
I'm not sure how that equals hours of googling etc
Yes it is just a rehash of that thread, but that's because that's the method that works for aussies. Only way to tell that is to flash a few, brick a few, or read this thread.
