I just got a new Blackberry. Does it work on its own or do I need additonal services added to my phone plan. I'm having troubles and I'm not sure what I'm doing. I guess I should call Verizon, but thought I'd check here first. When I ordered it (got an offer in the mail), the gal who helped me sounded new and I'm not sure she knew what she was doing -- maybe she forgot to add something to my service plan.
