Came across a problem that I noticed others were also having on some forums.
When you create a provisioning profile in apple's portal, then download it and try to go to target info to use it, it often isn't there. You try to click on Code Signing Provisioning Profile > Any iPhone OS Device, but it doesn't show on the list. I'm not sure if there is a more clever way to do this, but I can get it to show by right clicking and selecting "show definitions", then replace the hexadecimal values shown with what I find in /Users/YOURUSERNAMEHERE/Library/MobileDevice/Provisioning Profiles. Then when I right click again "show values", it's there.
Hope this helps someone =)
