Can i buy an iphone from AT&T and use it for Virgin Mobile?

I heard you can unlock the iphone 4, if i do that would i be able to take it from AT&T and use the same iphone 4 for Virgin Mobile? Or would i need a completely new phone? I know if it was AT&T to T-Mobile it would work but i'm not sure for other phone companies

Not possible… Virgin mobile doesn't use sim cards.
and only virgin mobile iphone will work on virgin mobile.

If its a Sprint or Verizon with a Bad ESN
and you flash it over to your network

Probably not. You would need to buy a Virgin Mobile iPhone. I have heard that Virgin Mobile doesn't use SIM phones, and since the iPhone is one of them, right then even if you were able to unlock it, it still probably wouldn't work right.

The 4S & 5 probably but not the 4. The 4 is either GSM or CDMA.AT&T is GSM & Virgin Mobile is CDMA. Can't use one on the other.

Yes you are correct. After Unlock your I-Phone 4 from AT&T Network lock, you can use with only GSM Network sim card.Virgin is CDMA Network in USA. Virgin has GSM Service in some other countries like United Kingdom(UK) … You can use that Virgin sim card. You can't use CDMA network… To Unlock I-phone 4 visit the site http://www.onlinegsmunlock.com/att-usa-apple-iphone-unlocking-service/rs7wp10/ get the Remote Unlock service and Unlock it easily… You no need to buy new phone. You can use other GSM network like T-mobile(as you said in question) except Virgin USA and other cdma networks.
