It depends on the person you get...my friend went through 3 droids just because he wanted an incredible. He bricked 2 and ran one over on a dirt bike...hes still stuck with the d1
They will probably send you a Droid. If the insurance policy is similar to the manufacturer warranty one, if you get 4 poor replacements then they will send you a Droid 2 or a DInc. I would assume they are similar since both are using Verizon as the middle man to get you a replacement phone.
