title: iOS provisioning and keychain generation
body: <p>I'm using Xcode 4.3.1 on Mac OS X 10.7.3 trying to provision to iOS 5.1 phone. First I used the Development Provisioning Assistant to create a provisioning profile. After dragging/installing the profile in Organizer, it says "valid signing identity not found". I continued with the Development Provisioning Assistant, got a new Development Certificate, installed it. But it didn't help. It's still "valid signing identity not found". After reading this topic on google and other people's solutions, I deleted all keys in Keychain Access, walked through the Development Provisioning Assistant again, did everything it said, but still didn't fix the problem. So I thought I needed a fresh start again. I deleted all provisioning profiles, certificates, keys. Then I redid everything, but no use. I also tried "Add to portal" in the Organizer, which only generated 4 certificates but still no keys.</p>
  
  <p>Should I restart my machine? Just kidding.</p>
