phone and keep my existing plan? I'm wanting to order the Samsung Impression from the Amazon Wireless website. I'm due for an upgrade already and I'm under a family plan with my family so, I want to keep the same plan. It gives me the option to do this, too. But, I'm wondering, how does Amazon know what plan I currently have? It asked me for my cell number to see if I was eligible for an upgrade and everything worked out but it never stated anything about my current plan and what specifics there are of it, so I just wonder if they know my actual plan. Sorry if that's confusing! Hopefully you can understand what I'm trying to ask.
