I purchased one of the Boost MObile CDMA Sayno Incognitos... I activated it. Used it for about 2 to 4 hours then called in. I told them I had an issue with the phone and that I wanted to put my number on an old phone I had. They asked for the DEC (ESN) and then told me to turn off the phone. When I turned it back on the handset (TOuch PRO 2) said Handsfree Activation contacting service.... within a few second it was programmed. If you buy a used phone you may need them to walk to through programming it manually. If you need help you can send me a message and then I can help you. I still have my original incognito so I can help you out with the porting of number or whatever. Just remember that you won't be able to do this until you activate first with a Boost Mobile CDMA phone. I have done this for about 15 people in my area. I live in the MD,VA, DC area.
