I guess this applies to all phones, but with the cost of this phone, I'm more worried about the risk. Is there a way to make sure, that when I'm buying from either eBay or Craigslist, that the seller wouldn't just claim the phone stolen once I have it? If I activate it on the spot with Verizon, can the previous owner still file it as stolen? Also, how would support work? Theoretically, if I bought the phone from Amazon, Verizon still wouldn't know right? Does it make a difference to them where the phone comes from in regards to providing support?
