Keeping the BlackBerry ON without first isolating it from push data allows new data to arrive and potentially overwrite existing evidence, compromising forensic integrity.

Removing storage media before network isolation is out of sequence and could physically alter the device state or damage volatile evidence.

Eliminating the ability of the device to receive push data ensures the current evidentiary state is frozen - incoming emails, messages, or synced data could overwrite or modify existing evidence before it is examined. This network isolation step preserves the integrity of the data on the device. It is a foundational principle of digital forensics to prevent any changes to evidence prior to acquisition.

Turning off the BlackBerry risks losing volatile memory contents and may trigger data encryption or wipe routines, and should not occur before network isolation.
