I called Verizon directly this afternoon when I couldn't find a local store that could confirm for sure they had 64GB version, and the very helpful Verizon rep tried to sell me the phone, but the system would not allow her. But, she ALSO volunteered the $100 trade in credit and explained how it worked both online and at B&M stores. Either way, it's processed as a credit on your bill down the road, so don't expect $100 off on the spot. I didn't go so far as to ask if "any" phone would qualify. She asked the condition of my "current" phone, so obviously, they would certainly prefer your existing phone (makes sense). I plan on trying to trade my old Sprint HTC EVO 4G. It's in exceptional condition, but has no value to me.
