Just noticing this and I've heard of some others talking about this the last few days.
Not all iOS ad-hoc provisioning profiles are shown in the Ti / AppC Studio configuration screen. What I see: http://www.screencast.com/t/xjw53dTGTM - Some of them are there but I'm expecting to see other ad-hoc profiles etc. When I go to the settings I see all of my profiles, which many of them are adhoc / ent profiles - http://www.screencast.com/t/w7K4fx5VO
This can consistently be reproduced on Ti Studio and AppC Studio.
