Frédéric is alerting us about that photograph where one can see a crashed iPhone on display at an Apple Store, oops!.

We're sorry for the poor quality of the photograph

As an evidence it runs Unix-based system, one can read:

Single user boot -- fsck not done
Boot device is mounted read-only

If you want to make modifications to files:
/sbin/fsck -fy
/sbin/mount -uw /

If you want to boot the system:
exit

Jul 21 00:43:00 : can't execute /sbin/sh for single user: No such file or directory

Frédéric nous alerte sur un iPhone photographié crashé dans un Apple store !

Nous sommes désolé de la mauvaise qualité de la photo

Une preuve, s'il en fallait, qu'il tourne sous un système Unix ; on peut lire :

Single user boot -- fsck not done
Boot device is mounted read-only

If you want to make modifications to files:
/sbin/fsck -fy
/sbin/mount -uw /

If you want to boot the system:
exit
