I posted this in the AT&T forum also:

I should call customer service to ask this question, but I'll ask it here first. I'm currently a Verizon customer and I want to switch to Cingular/AT&T. On www.amazon.com I found a deal where I can get $200 back and be able to pay my early termination fee. The only problem is that when I checked on amazon to see if I could keep my number it said that it wasn't available yet. If any of you know any way that I can keep mt number but still be able to get the phone and pay off my early termination fee let me know!
