It is my understanding from other posts that Verizon does not unlock their phones, so you would not be able to switch to Sprint. I also seem to recall that they are on two different networks (CDMA vs. GSM) so that would pose a problem also. If you search this forum, you should find more information.

Sprint is also on a CDMA network like Verizon, but the two are not compatible. The chance of being able to "flash" a Verizon phone to Sprint successfully is quite low; it's safe to say it's impossible. This is because Sprint will not activate a phone whose ESN does not match their database.

xtremecarbon is correct. Both Verizon and Sprint are CDMA networks. However, each carrier can only activate phones that match their databases. Both Sprint and Verizon will unlock the GSM portion of an iPhone 4S for international travel.

Both Sprint and Verizon do use the same network and could use each others phones with no problems at all they just choose not to. All the iPhones now are exactly the same for all the carriers. This is why you can roam between Sprint and Verizon or ATT and Tmobile the hardware and software are the same. It is also true for other phone makers. The carriers use this as a reason for you to not leave and go to another carrier because you will have to put out the money for a new phone. This is also the reason you can roam outside of the US or other countries. The only thing they have to do to get it to work is put your phones info into there system and it will work. I worked for a carrier (Sprint) there were times when phones were shipped out and not in our system. We would send a request to have it added and about 24 hours later it would be in and working. I wish congress or whoever would pass a law or something to let us move our phones around as there is no reason it cannot be done.

That is absolutely false.
This is why you can roam between Sprint and Verizon or ATT and Tmobile the hardware and software are the same.
Also completely incorrect. Verizon and Sprint are CDMA carriers. AT&T and T-Mobile are GSM carriers. You can not use a GSM phone on a CDMA network and you can not use a CDMA phone on a GSM network. Some CDMA phones are considered "world phones" as they contain the necessary hardware, as well as a SIM slot so that they can be used on GSM networks. No Verizon or Sprint phone, however, can "roam" onto any US GSM carriers network. The only exception is the Verizon iPhone 5. The SIM slot on the 5 is unlocked and it is capable of using a SIM from a US carrier. The 4S, even with the SIM slot unlocked by Verizon, can not use any US carrier other than Verizon. The Sprint 4S and 5 can not use any US carrier other than Sprint.
Some CDMA phones can be "flashed" to work on a CDMA network other than the one they were intended for. The iPhone can not be, and even if it could, Verizon and Sprint will not permit you bring your own phone.

Not trying to start a fight but could you explain how a phone can roam between Verizon and Sprint(CDMA) or ATT and Tmobile(GSM) if my statement is false? As far as CDMA and GSM yes you do need that carriers network thats why I put Sprint and Verizon (CDMA) together and ATT and Tmobile(GSM) together. I should have been more clear on CDMA GSM in my post.

In that case, I misread your statement to mean that you could roam from and to any of the 4 carriers you listed. Since your statement that Verizon and Sprint use the same network is so outrageously wrong, my brain interpreted the following statement as equally incorrect.
Sprint and Verizon do not use the same network. They use the same type of network. There is a huge difference. If you actually worked for a cellular carrier in any capacity above that of a sales drone in a mall kiosk, I would expect you to know that and, equally, to know that the distinction is critical in any kind of technical discussion.

Again not trying to argue but I seem to have missed something in my training. They both use the 1900 MHz band but Verizon does also use 800 MHz in most area's and they both use evdo Rev-a. I am wondering what the huge difference you are talking about is other than Verizon having WAY better coverage?

They are physically distinct networks. They have their own towers. They do not use the same network.
I have WiFi at my house. You have WiFi at your house. Are we on "the same network"? Of course not. Are we using the same frequency band? More than likely, yes.
If Sprint and Verion were using "the same network" the coverage would be exactly the same for both of them.

Ok clearly I should have been more clear in my post as to the same network being the same TYPE of network like your example with wifi. I think we are on the same page now as far as the networks go so I will end by saying this. Thank You for your service!!!!
