The software I use is directly from iDEN
PC Software Applications
Its the media downloader. Its been awhile since I did it, I think you need to download the Motorola USB driver to make it work with the USB cable.
It works great, but you cant delete pictures, just copy over.
A also suggest the phonebook manager, You can upload your phonebook list and make a file on your PC, and even print out a copy. Comes in handy for me.
