Export non-Camera Roll Photo Albums to PC? Is there any way to export non Camera Roll or Photo Stream photo albums from an iPhone to a PC? There are a bunch of "free" software online than can do this, but they all require you to buy the software to transfer the photos, or they can only transfer a few photos before needing to buy the software.

The iPhone is hooked up to the computer right now and I can browse the DCIM folder, but those are only Camera Roll pictures. I'm not willing to jailbreak the iPhone either as it's not mine.
You can only transfer photos out of a device that were taken on the device or are otherwise in the Camera Roll. Photos synchronised to a device over iTunes are not able to be synchronised in reverse or otherwise taken from a device.
