Even if you manage to unlock your Sprint PCS handset and change the NAM settings, it is unlikely that Verizon Wireless or whichever other provider you wish to use will allow you to use this handset on their network. With GSM phones there is pretty much one standard that most carriers abide to, thus it is easy to swap a sim card and use another network. CDMA carriers on the other hand use highly customized firmware on the equipment that they sell, which isn't necessarily compatible with competing networks. That said, if you do persuade your new carrier to activate your Sprint phone, more power to you, but be aware that certain features such as text messaging and web browsing may not/probably won't work properly. There are other issues with PRLs (Preferred Roaming Lists, which basically tell your phone which towers to use) that I won't go into here, but suffice it to say that if you try and bring a phone from one CDMA carrier to another, you're asking for a lot of trouble.

I'm not sure about CDMA unlocking (Sprint, Verizon, Nextel) since I never seen it done, but GSM unlocking is easy.
BTW, Nextel uses iDEN, a proprietary Motorola cellular technology, and not CDMA.
