In fact, I thought I already did. I posted another reply but it seems to have vanished. Heck, I even posted it twice because it wasn't visible but the system said it was duplicate so I thought it would come out eventually... Anyway, here is the third try (luckily I copy pasted the reply...).

I've been meaning to write a blog entry about this subject, but I've been a bit busy. You can't use Android/iOS/BlackBerry apps in format they are distributed in app stores.

The support means that if you have the web app code used to create these native apps (using PhoneGap Build cloud service or packaging them manually), you can install that (.wgt file) directly to Hydra and it should be API compatible (as far as Cordova's own MeeGo API implementation goes, it's not perfect yet). So if your a developer doing Cordova apps, you can run/test and distribute them for Hydra.
