Just spoke to O2 - the official release date for the fantastic new XDA II is now going to be 1st November.
And in unrelated news (now look, I said it's unrelated and unrelated it is! All right!) my current XDA broke down over the weekend and needs replacing. It broke down, I tell ya! It did. And needs replacing. It does. By a new one. A new XDA. A brand new XDA.
