A configuration profile is required to install security certificates to iPad.
Created a configuration profile with iPhone Configuration Utility 2.2. Utility recognizes iPad, but clicking "Install" button on "Configuration Profiles" page does nothing (no error message, nothing). Sending the profile by Email to iPad gives "Mail Cannot Open This Attachment" error when opening configuration profile.
I have previously created and installed profiles successfully to iPhones and the profile created above works in iPhone (3.1.3).
