Okay, I've installed vB 4.2 now, a few issues:
Android isn't supported when using Firefox; only the Firefox icon is shown, and the reason for that is because Firefox doesn't show the version number of Android. Here's the UA:
Mozilla/5.0 (Android; Mobile; rv:14.0) Gecko/14.0 Firefox/14.0.1
Using Konqueror:
Mozilla/5.0 (X11; Linux x86_64) KHTML/4.8.4 (like Gecko) Konqueror/4.8
It shows Konqueror as 4.8.4 but isn't that the KHTML version?
When using Chromium, it shows the Chrome icon. It's possible to show the Chromium,
I've done this with my plugin. Here's the UA for Chromium:
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.168 Chrome/18.0.1025.168 Safari/535.19
Moreover, the Chrome icon is the
old and outdated Chrome icon, in my opinion, it would look better if you used the updated
2011 Chrome icon. And the 2011 Chromium icon.
And then there's this bug that keeps deselecting all usergroups in admincp, so basically no one can see the icons. Not sure what's causing this. Maybe installation of new plugins or something. Shouldn't be like that though, because it's a pain in the ass to select all usergroups.
If you need to identify a user agent string, you should use this site:

And its database is most helpful:

I would also prefer if you resized the icons to 24 pixels in height, it looks better than 19. You can use my icons, I even have customised versions of Android for each major release (ICS, Honeycomb, CyanogenMod etc.) and I also have more icons than you.
