I touched upon the release of Android 4.0, also known as Ice Cream Sandwich, back in October:

That was based upon the official docs and emulator, but about a week ago I finally got an actual device in my hands in the form of the Galaxy Nexus, and I find it a lot easier to test on real hardware so I thought I’d revisit the OS to test out some client certificate related features. (The eye candy factor is greatly improved, but it’s not like you can’t find tests of that all over the web.)

I said that certificate support was improved – for instance the support of client certificates with the Google-supplied Exchange ActiveSync client. This implied there might have been some improvements for the browser as well, and the short answer would be yes
