I need to make a adhoc version of osprey for a potential publisher never done this before will it mess up my provisional profiles that i use currently a little worried that it will mess with my current development settings…?
I recently set up some adhocs myself. It does not affect your Development Provisioning Profile as an Adhoc Provisioning Profile is set up for Distribution not Development.
Here is a good article for creating and sending a Adhoc build to clients to view Installing an Ad Hoc Distribution - iPhone How To Docs - Inner Fence
cheers dude
