I don't believe that is an option with that phone, According to the reviews - ""You can transfer photos off the phone via a multimedia message, upload them to an online album hosted by Sprint, or transfer them to a printer via Bluetooth or PictBridge service.""
I, too, would like to get a USB driver for this phone. I don't want to do anything fancy: just charge it from my computer and transfer photos. When it was sold to me, I was told I could transfer photos. Was the salesperson lying?
