Is it possible to unlock a CDMA iPhone 4S (from Virgin Mobile) to use another SIM in it? My friend has an iPhone 4s, it was bought from in the USA from Virgin Mobile. I want to do a factory unlock (unlock the SIM). I already know how to jailbreak, would jailbreaking work? Any help would be appreciated.

I read this answer, but was told the following:


  Virgin Mobile USA iPhones are CDMA. If you need a refresher - CDMA
  means the phone is locked to the network forever.
  
  You will never be able to unlock your iPhone from Virgin Mobile USA.
  They do not use sim cards - so there is no way to unlock it.


Is that correct? My question is, is it possible to unlock CDMA iPhone 4S from Virgin Mobile?
Of course, it's possible!  

Simply buy a Gevey Turbo SIM ultra S CDMA.  Note: type "geve" into google and watch it autofill with "gevey sim".  Good news- You're in luck because the price is not bad for the CDMA Gevey SIM turbo at this time. 

sometimes, they're close to $100.  only $35 right now.

also, i've included some other links to help explain
