EDIT: Any existing VZW subscribers who have received your iPhone 4S, would you mind calling and seeing if they will do a SIM unlock for you and report back? ----- Over the past few years, most VZW global phones have had their GSM bands locked to VZW's own SIM card. Once you were a VZW customer for at least 6 months, you could call VZW Global Support (1-800-711-8300) and they would give you an unlock code for free so you could use non-VZW SIM cards while traveling abroad. The process is a bit different to unlock the iPhone; carriers must send your IMEI to Apple's server and then you apply the unlock through iTunes. Will we be able to do this through Verizon?
