On October 7 when Windows phone was launched, the HTC Touch Diamond2 was made available with Windows Mobile 6.5 from Telstra.

Before we launched 6.5, Optus and a lot of open channel/retail partners were selling the HTC Diamond2 powered by Windows Mobile 6.1. If you own one of these then good news – the official Windows Mobile 6.5 update is available.
