UNLOCK; Samsung SPH-I700

You can take it to any CDMA based carrier (i.e., Sprint) and they will provision it for use. It is very easy in CDMA world.

They sell these already unlocked on ebay by the hundreds. If you're attached to the one you have, you can find a cell phone store that will unlock it for you by visiting unlocktotalk.com to find a local store or send it in to unlocktotalk.com. They have a CDMA unlock mail-in service if there is not a local cell phone "flashing" store which provides this service in your area that can reprogram your phone to work with the new CDMA service of your choice.

I suggest you log on to www.unlocktotalk.com to get details. It only costs about $20 and it is 100% legal. They openly advertise that they can unlock CDMA cell phones (or GSM-in a separate section of their website- if you need them to.) You can do it at a local store or if you're sending it in, pay through PayPal and only pay if they get it done.
