A forensic investigator is acquiring evidence from an iPhone.

Comprehensive and Detailed Explanation From Exact Extract:

Before connecting an iPhone to a forensic workstation, the investigator must ensure that the phone doesnotsync with the computer automatically. Automatic syncing may alter, delete, or overwrite evidence stored on the device or the computer, compromising forensic integrity.

Jailbreak mode is not necessary and can complicate forensic analysis.

Powering off the device prevents acquisition of volatile data.

Root privileges (jailbreak) may aid access but are not mandatory before connection.

NIST mobile device forensic guidelines emphasize disabling automatic sync to preserve data integrity during acquisition.
