I agree that it's not the best case that Apple needs to bring it "in the back" and to need to unlock it but if you can access the phone's diagnostics from outside the locked phone done it's already insecure. The fact that even apple has to have me unlock my phone tells me that not even their diagnostic tools work outside the lock screen. That sounds beautifully secure to me. And I agree with userbinator in that "you're going to have to let the plumber into your house if you want him to fix your broken toilet.".
