iPhone CDMA FAQ: How to inject?

[upin ipin]

I'm from Indonesia and few days ago i bought an iphone verizon with bad esn on ebay.
I bought it because some said that bad esn wouldn't affect if you use overseas carrier for example in Indonesia like telkomflexi, is it true?

I just watched youtube video: [Only registered and activated users can see links. ]
i read the tutorials:
These are the steps I took to flash(not perfectly) my iPhone 4:
1) I unlocked and jailbroke my iPhone using Greenpois0n
[Only registered and activated users can see links. ]
2) Then dial *22804 send then press 5 from your iPhone keypad , or say "Roaming List" at the prompt. than it will download the roaming list to your iPhone, when it finishes it's done.
3) Than dial *228 and select option 2 if you have metro PCS account to switch your phone and that's it.
*(this wont work if you have a bad ESN)
4) if you don't have Metro PCS just go to Metro PCS and activate your iPhone.
*If you have a bad ESN, You will NOT be able to activate your iPhone until someone adds the MEID to the network.(this is where you go to a metro store and hope they do it)

sentence with bold, what is those codes use to? is there any code that i need to know for iphone cdma?

is it only for MetroPCS carrier?

i didn't saw if he do custom for iphone PRL file like some tutorials that posted here about how to flashing iphone cdma, is it possible?

in my iphone, i only see MEID, is it same with ESN?

if not, how to find it ESN then?

how to set up the NAM, or is it applicable already with iphone CDMA?

I've injected an Android phone (bundling with Verizon) before this, the some things i've done were:
inject it with new PRL that suit to new carrier (in mycase telkomflexi)
and then register the ESN to carrier then akey released with new number
after that i call for OTA activation, and now can accept and send call and text.

Is the iphone also as simple as that?

i will only use iphone cdma for call and text only, for browsing i'll choose via hotspot.

If i can give an advise maybe Rich can make 1 new thread or can do it here.
Make some tutorial with pictures guide like in iclarified, so some people like me from overseas that want to know about how to inject iphone can do it right.

Many thanks for the replay

ps. I'm sorry for my bad english
