I could be off on this, but I believe while this was an issue in beta 1, this has been resolved as far as beta 2 (or at least 3) and should be working already (and hopefully still working in beta 4, unless some sort of a regression popped up).

As of beta 2, I've been able to accept certificates, however, I've been unable to connect to the secure wifi (eduroam) at work. It simply does not receive an ip-address, but accepts my credentials and certificate. Haven't been able to test it with beta 4 though.
