I agree, the whole point of the logout bug is that the keychain is locked, and that happens for a reason. I came up with a different solution that worked great for us:

Just pause the startup process of the app (in a non-blocking way) if accessing the keychain fails at startup. Then during applicationDidBecomeActive the startup continues with access to the keychain data. That way we don't weaken the security of our customers.

Good point. We thought about this as well, however solving this bug this way we wouldn't be able to continue background uploads every time the iOS7 'reboot' bug had occurred, which was fairly often.

It's a trade-off between user experience and security. As soon as Apple fixes the reboot issue, we'll increase the security level back to kSecAttrAccessibleAfterFirstUnlock.
