no, it doesnt.That option leads to a screen forcing you to select one of several limited data plans. There's no way to keep unlimited data that I could find.there is an option for keeping your existing plan through the costco deal. above the price there are links for upgrade and 2 year. click upgrade then add to cart. select the option "Upgrade your phone and keep your current rate plan", click next, put in zip code, review your cart. its worth nothing that it also comes with a DROID 3 KIT which consist of a pouch, a screen protector, and car charger for FREE
scroll down and hit next, enter zip code, review cart. youll need to enter your mobile number as well as your verizon account password later on.
