Hi folks, I've been trying to think through this but haven't figured out what the best way is yet. I have a white 3gs (32gb) on AT&T and am trying to figure out what the most economical way to switch over to Verizon iPhone 4 would be. Sell my 32gb on eBay and sign up for VZW? Or trade in using the VZW offer? (How do early termination fees kick in to this?) Any advice would be helpful, thanks.
