Can you access ice on a locked phone?

Could you please elaborate on the feasibility of accessing the contents of a locked phone, particularly the frozen data or "ice" as you've termed it? Is there a technological means or software tool available that allows for such access without the need for the phone's unlock code or other authentication measures? Additionally, are there any legal implications or ethical considerations that should be taken into account when attempting to gain access to locked phone data? I'm curious to know if this is a common practice in the field of digital forensics or if it's reserved for specific scenarios and how it might impact privacy rights.
