[sim pin] prompt on boot but after greeter

I remember design requested this explicitly. The reason is that we don't want the user to forget to enter the SIM PIN, leaving him with a locked SIM and not being reachable for phone calls.

Hmm the linked bug does say "immediately after boot", am I misunderstanding something?

We (I, mterry and Olga Kemmet) had a short discussion last week if it would be possible to have the automatic SIM Unlock dialog appear after the greeter. Please include them to this discussion.

So the design was always to have the SIM unlock dialog waiting under the greeter.

But because of the way the dialog is implemented as a notification, it's technically very difficult to do that. (Mirco is working on fixing that by separating the concept of dialogs and notifications.)

So another possible solution is to just trigger the SIM unlock dialog only once the user drags the greeter away. But that looks bad (the user sees the dash or lockscreen first before we flash a dialog in their face).

So we ended up implementing the "next best thing" which was to just show the dialog on top of the greeter after booting.

To properly fix this, we need the dialog/notification refactoring that Mirco is working on.

Just to sum up: If we reforge the authentication screen into a similar dialog as we currently have for WiFi password input, then it can sit basically anywhere in the UI.
This would allow to sit it even on top of the greeter because users will see what is in the background and it would be the first thing they are informed about. This way we would cover the issue that SIM PIN, Greeter and passcode/passphrase screens are visually too similar (by mistake putting in your passcode instead of SIM PIN and vice versa). Since the SIM PIN authentication can be triggered from System Settings, indicator menu and possibly later from apps which require SIM as dialer and messaging (on action), it would make sense to give it the same behaviour as other dialogs triggered from the system.

As mterry pointed out we might need to wait for the "dialog/notification refactoring that Mirco is working on."
