Yes, Verizon has limited the Bluetooth capabilities of their phones. Are her pictures saved on a TransFlash card(if she has one)? If so, you can use the SD Card adapter that came with it to transfer the pictures to her Mac, provided that she has an SD card reader. Motorola does sell a USB cable for the E815. My GSM V635 supports data transfers through Bluetooth, and it came with a TransFlash card, and a USB cable, but I'm only using the USB Cable. I found that the USB cable only reads the memory on the TransFlash card, not the phone memory. I'm not sure if a USB cable connected to an E815 would perform the same way as if it was connected to my V635. I hope this sheds some light on your problem.
