Under Settings> Location and Security, there is a section that allows the user to import certificates. There is also the option "Use secure credentials" that "Allow [s] applications to access secure certificates and other credentials." I can’t find a mention of how to do this in the documentation, and there are very few mentions of this on the Internet, except for people who use it to connect to Wi-Fi networks that are protected by a certificate. One of the only relevant things that I discovered is a message stating that access to these certificates is virtually impossible for regular applications. It's true? Does anyone know how to access these certificates if this is not the case, or the documentation that states that this is not possible?
Take a look at this Android issue for a discussion on this topic: http://code.google.com/p/android/issues/detail?id=11231
The settings screen for installing root certificates can only be used for VPN and Wi-Fi, unfortunately.
