T-Mobile has released AKU2 MDA Vario (HTC Wizard) for German(-speaking) users

As always, the great folks over at XDA-Developers were the first to report about the new, official, AKU2-compliant, German T-Mobile MDA Vario (HTC Wizard) upgrade. At last - I'd say, given that German MDA Varios receive updates much more rarely/later than other HTC Wizard rebrands. The update is available directly here; the official update homepage can be found here. There is only one problem with the upgrade: it's not compatible with the BlackBerry Client Software Version 2.1 (referred to as BB in the above-linked thread) (unlike with the previous version), as can be seen for example here.
