no. they have a "trade in" program of some type, but i believe they give you a verizon gift card that you could use towrds the purchase (at full retail price) of a new device and i suspect you would be lucky to get $100-200 for the incredible 2. Your best bet may be to see what you could sell it for on ebay and maybe only have to pay a difference of about $200 or so??
it looks like incredible 2's (in good condition, used) are going for just over $200 on ebay.....so you would still have to cough up quite a bit to purchase a new iphone.
