The CDMA radio is fully functional in the unlocked GSM iPhone 4S. How do I know?

Well, I just purchased one from Apple and decided to mess around.

Without a SIM, try the * OTA codes for CDMA:

*22801
*22802
*22803
*22804
*22805

In this case, once I hit *22801, I got a "Welcome to Verizon Wireless". I think *22804 was Sprint.

Of course, this doesn't help because if you look in Settings->General->About on an unlocked iPhone 4S, you don't see a MEID, only a IMEI.

What's the difference between a CDMA iPhone 4S and a GSM one? The MEID is missing from the GSM versions. Also, although the IMEI and MEID are the same length, let's take a look at the prefix:

IMEIs are typically 01 for the prefix here in the US.

If you look at the IMEI or MEID of a CDMA iPhone 4S, you will see the IMEI and the MEID both are identical, and start with "99", which is the prefix specifically designed for dual technology (CDMA/GSM) phones.

So, we have two issues with an iPhone 4S (non CDMA version) on a CDMA carrier:

1) There is no "valid" MEID that shows up in Settings->About->MEID - i.e. it doesn't even show up on the menu!
2) Even if it did, it traditionally copies the IMEI of the phone, which has a 01 prefix. IMEI and MEIDs share the same namespace. A CDMA carrier would see the "01" prefix and go "Oh, that's a IMEI, not a MEID." They would have to be a prefix of "99" to work on their network correctly (or A0 or some other valid MEID prefix). Of course, if you set the IMEI to something like A0 or another valid MEID prefix that's NOT "99" you stand a chance of your GSM part not working, because "A0" is in the IMEI namespace.
3) If you note the Apple MEIDs on CDMA iPhone 4S'es, you notice that the IMEI and MEIDs on both are the *same*. IMEIs cannot be hexadecimal, so you will always note the MEID has only decimals numbers in it, no hex, unlike a traditional MEID, which may start with Hex >A.
4) Yes, I know that if you're an enterprising hacker, you can change the MEID to something different than the IMEI on a dual mode CDMA iPhone 4S. However, Apple's OOB models have both numbers being the *same*.
