For all you future iPhone on Verizon users, you should keep the following in mind: 1. If your iPhone becomes lost or stolen, contact Verizon to let them know ASAP. They will block the ESN so the phone will not be tied to your account. What's cool about Verizon is the fact the phone is now worthless, as it can never be activated by anyone but you again. Having your phone stolen sucks, but at least you know that your phone is a mere brick and is not being enjoyed by the thief. On GSM, all the user has to do is pop in a SIM and the phone works again. 2. Accounts that are past-due will have the ESN on the account permanently blocked until the account is up to date. Keep this in mind when you are ordering used CDMA iPhones via eBay or Craigslist. If the phone was stolen, or the account holder is past due on his or her account, then the phone will not work. There is no pleading to Verizon to get them to activate it as they will refuse to. Only the original account holder can activate a phone with a blocked ESN by reporting that the phone is no longer stolen or by paying the account balance. Before paying the seller, always contact Verizon with the ESN of the phone you are buying to ensure that it is clear and ready to activate, otherwise you maybe stuck with a phone that will work fine but be as useless as a paperweight.
