Thanks to this post by Jon Armstrong and the "bitpim" software he refers to, I finally have a way to extract photographs from my Sanyo PM-8200 phone without zapping them across SprintPCS's digital data service.
I had already bought a USB data cable for the phone, so all I needed were current USB drivers for the phone and bitpim. I did struggle for a while with the hardware until I realized that the caller ID program on my computer was grabbing access to the phone and locking bitpim out. Once I disabled the caller ID software, bitpim worked fine.

Hi I was curious how you found out it was caller ID and how you shut it off? My PM-8200 is acting the same way and informing me that I can't access it because another process is already using it. =/ Thanks for any info in advance!

I was using a Windows machine on which I had installed the "PhoneTray Free" caller ID program. I have an old dialup modem attached to the computer just for caller ID and the occasional fax transmission, and PhoneTray watches that modem for incoming calls. Apparently, when I connected the PM-8200 to the computer, PhoneTray recognized it as a modem and grabbed hold of it as well. I just quit PhoneTray, reconnected the phone, and it worked fine.
Depending on what process is locking access to the phone, it may or may not be that simple for you. I'm sorry I don't have more detailed advice for you!
