If the product was passed the trial stage you'd be seeing a lot more reviews & downloads everywhere.
At the moment the downloads are virtually solely coming from Indonesia, where around 1,500 users per day are downloading the app purely by word of mouth. We don't even know which Indonesian Telco's are carrying the product, it just be one of them !!! (Although I suspect its 2 plus).
Downloads will be population based eventually, Australia will be way down that list, just a speck. They might be much higher up the Dataflex tables thou, when it comes out.
