Distinguish between different causes of VOIP application start

Question

VOIP application are restarted automatically in iOS in several cases:

I am looking for way to distinguish between them.

I checked launchOptions from didFinishLaunchingWithOptions, but both for Reboot and Initial install are nil (I didn't check for a crash).

I am looking for a way to distinguish programmatically these three cases. I am fine with private API's.

@meaning-matters: Do you want to put it as an answer (it's quite interesting info and I would be happy to upvote it)? — Victor Ronin, Apr 30 '13 at 22:31
The user can also kill the app explicitly, which won't look much different to rebooting the device. — tc., Apr 30 '13 at 23:14

Initial install can be detected by saving something in NSUserDefaults; if it's not there yet ...

Reboot vs. Crash is being discussed elsewhere, like here.

And perhaps looking at iOS uptime might help. Could be combined with NSUserDefaults.
