Howdy all.. new to the forum so forgive me if this has been asked before.. but i just bought the N1 in Australia on Vodafone

So I've been playing around with it and i cant seem to get the gps going but i dont think its an issue with the phone itself but more on the google development side so can anyone tell me if google is working on the maps for Australia, if so how long until release. and what the other good alternative navigation apps are that i can use til then?
