We already had word that the Xperia X10 would be launching in Australia with Telstra. At the time we didn’t have any release info but, the handset has been released this week. The Xperia X10 is available on pay as you go for $1099 AUD or, if you take the phone on a $100 a month tariff, the handset will be free. As expected the contract length is 24 months.
