I don't know about that phone specifically, but it may only be available as a modem, not for file transfer.
I Googled it and it looks like the 325 is Verizon's version of the phone, which would mean that it's running Verizon's interface software, not Motorola's. Verizon is known (notorious?) for wanting you to buy ringtones, wallpaper, games, whatever, through their service, expensively, rather than connect it up yourself. My wife's phone is on Verizon, and I bought the connectivity kit for it. All it does is set it up as a modem. The Bluetooth connection is also only for use as a modem, no file transfer or networking. Fortunately, hers has a mini-SD slot, and I can put stuff on the card when it's in my PC, and the phone will see it. That lets me get pics out of it, too, without having to email them from the phone, which has a fee. As I understand it, if I had "upgraded" the phone to Verizon's "Get it Now" service, which was not built in at purchase, I would not be able to do even that much.
For this connectivity reason, and this reason alone, I steer people away from Verizon when they ask me who to use. My wife's LG phone works great, the coverage is awesome, calls are clear, the plan is reasonable, but I feel that I should be able to configure MY phone without having to get it all from their EXPENSIVE downloads.
