Switch GSM to CDMA?

I had an unlocked iphone5, which model is A1428. I'm wondering how to switch gsm to CDMA?

You cannot. For all practical purposes, in order for a phone to work on a given CDMA carrier, it must have been sold by that carrier.

IPhone 5 - GSM to CDMA?

I'm on Verizon, but I'm stuck with a GSM iPhone 5. I was on vacation when a relative from overseas thought my current phone looked shabby, and bought the 5 for me.. Unfortunately, the IMEI can't be recognized by Verizon, as it is most likely a GSM phone.
Is there anything I, Apple, or Verizon can do to switch the phone from GSM to CDMA? I realize other carriers such as AT&T can accept GSM phones, but I don't care to switch carriers because of a phone someone gave me as a gift.
Just to clarify--not all iPhone 5's are made the same, right? There is a physical internal difference between Verizon-approved iPhones, and GSM iPhones? It's not like I could get my tech-genius cousin to tinker around and get it to work, I'd actually need to change some physical network receptor in the phone?
Is there anything to be done other than switching carriers or selling it on Craigslist? Like I said, it was purchased abroad through am authorized reseller, so on don't think any Apple stores could help me.. I basically have a $600 brick sitting in my room lol.

You already posted your answer, sell it on Craigslist use that money towards a new Verizon iPhone. You can make a Genius Bar appointment at the Apple Store or call AppleCare and ask to be transferred to Customer Service, but the answer will still probably be no.

No.

How to find which model of iPhone 5 I am using? and is that GSM or CDMA?

How to find which model of iPhone 5 I am using? A1428 or A1429 ? Is there any short code you can dial in and check the model number ?
And which is GSM or CDMA out of this model.

If you purchased the phone in the US with an AT&T contract then you have the locked CDMA A1428 version of the iPhone 5.
At the moment and if the contract is a new contact, then you won't be able to get the phone unlocked at the moment and no, you won't be able to use it in your home country. You will also have LTE 4G compatibility issues too and your phone will only work on 3G and also you need to remember that iPhones are only covered by country specific warranty, so it is only covered in the US, so if you go home and then have a problem with your phone, you will have to come back to the US to get it repaired.
You need to approach AT&T about whether they will unlock your phone for you as they are the ONLY ones that can do it, but the answer to your question is no and if you had wanted to use your phone at home, then you should not have purchased it in the US. The best that you can hope for at the moment is to use it on international/roaming.
If you purchased your phone in the US, then it will be a CDMA phone. You don't have a GSM phone, but GSM phones are unlocked anyway and these are the ones that are selling in Canada and the UK.
If you have your phone on an AT&T contract then ultimately, AT&T are the only ones who can help you with any questions regarding unlocking and they are the only ones who can unlock it for you, noone else.

what is the best Gsm or cdma iphone5 ?

All iPhones (with the exception of the iPhone 4 CDMA) will work on any GSM network worldwide as long as the device is unlocked.
LTE coverage is limited by the carriers roll-out and the model of iPhone. The A1428 is designed to use the LTE bands used by North American GSM carriers. The A1429 utilizes the LTE bands used in the rest of the world.

Yemen is not listed as there are no LTE networks, as per this Apple Doc.
Also that Apple do not sell iPhones in Yemen, officially.
Moreover, CDMA iPhones are for a specific operator whereas GSM unlocked iPhones are available.

I HAVE AN IPHONE 5 A1429. MY ITUNES IDENTIFIED AS (GLOBAL) VERSION BUT USE A SIM CARD. IT'S MY IPHONE GSM OR CDMA AND CAN I USE FOR AT&T?

If you are able to use the iPhone with sim cards from different carriers so you know it is unlocked, then it should work with an AT and T sim with the permission of AT and T.

Does the iPhone 5 require a factory reset to switch from GSM to CDMA

Before I ordered my iPhone 5 from StraightTalk I explained that I wanted to use it as a CDMA (Verizon) in the US and as a GSM (Vodafone) in Europe.
I specifically asked if the phone would become a CDMA phone again when I removed the Vodafone GSM Sim after returning to the US. The answer was Yes.
The CDMA function worked well in the US and the GSM function worked equally well in Europe.
However, when I did remove the GSM card, the iPhone 5 stopped working.
According to StraightTalk, the only way to return to the CDMA function is to have them do a factory reset, which means loosing all data and downloaded apps.
Of course, nobody told me that when I asked the question.
Does anybody know if this is a requirement for every iPhone 5 or just for StraightTalk phones?

According to StraighTalk, their "resetting" will cause all data to be deleted. It does not make sense to me either.
After I removed the SIM card, the mesage in the upper right corner said "No Service".
Resetting Network Settings made no difference.
When I talked to StraightTalk they made me dial some specifice codes. TFW service showed up in the upper left corner but they could not get it to work.
My mobile number is still valid. When I dial it from a landline, I get my voicemail.
As far as I know, StraightTalk uses the Verizon network for CDMA coverage (even if it says TFW on the phone) but I don't know how they tie into that network.
The problem is that the StraightTalk people seem to work from a script that provides standard answers. They may not know what they are talking about or they they do not want to make the extra effort to resolve this problem.
Either way, I am stuck with these people. If someone can tell me what should be done, I can ask them to take the necessary actions. Otherwise, I may have go through the exercise of making sure that all data has been synced with my Mac and then download all data and apps after StraighTalk had one their thing.

Possible to use iPhone on GSM and CDMA networks?

If I have a SIM for one of the iphones that supports versions of both CDMA and GSM, could I actually switch between, say, Verizon in the US and foreign networks wihile overseas?

The only phones you can use on Verizon's network are ones that were originally sold as "Verizon" phones. This is true of, as far as I know, all CDMA carriers. Verizon will unlock the GSM side of an iPhone 4S for international use for their own customers. Other CDMA carriers have other policies. The Verizon iPhone 5 and later are unlocked and will work on any GSM network.
An unlocked phone purchased from the Apple Store will not work on a CDMA carrier.

Does the iphone 5s A1533 works at GSM and CDMA?

My IPhone Was Purchased From USA.

CDMA does not use a SIM card for its network connection information (only for LTE data connection). So a CDMA iPhone has to be pre-programmed for a specific CDMA network, and will only ever work on that one CDMA carriers network.
So if you have a USA CDMA A1533 it will only ever work on the specific USA CDMA carrier it was sold for. If its GSM SIM slot is unlocked, then it will work with other GSM carriers, but it will never connect to any CDMA carrier other then that one carrier it was pre-programmed for.
The GSM only A1533 (AT&T and T-Mobile) has no CDMA capability at all.
