title: Xcode 4 - Lost Certificates and Provisioning Profiles, how do I recover
body: <p>I recently had a crash on my Macbook Pro. The disc became corrupted and unbootable. A new disc was installed together with Snow Leopard and Xcode 4. I also recovered 4 (published) applications and one in development from a backup. All are safe and well and working except, I don't have the development certificate and provisioning profiles. I have attached the iPhone to my machine and the Team Provisioning Profile, and a specific profile for the app currently under development seems to have been recovered from the device but I'm uncertain how to recover the Certificate, or whether to create a new one (the published - distributed - apps profiles have expired so I'm not concerned about them) an. I currently get a 'Valid signing identity not found' message for each profile.  I need some help/advice. There is nothing left of the old disc to recover from and I'm afraid I didn't export any Provisioning Profiles. </p>
