Can I get an iPhone 4S for Metro PCS?

Well, I want an iPhone 4S, But I have Metro PCS.
I was wondering if I could unlock an iPhone 4S from Verizon and switch the carrier to Metro PCS.
But, is that possible?
And how can I unlock the phone?
(Tutorials would help.)
Btw, I only have Metro PCS, because it's cheap… Lmfao.

No you can't you can't because metro uses CDMA and the iPhone uses gsm the only way you might be able to do it is with a iPhone 5 but I doubt it I know you can put it on there I know you can with t mobile by unlocking the sim

MetroPCS is a CDMA provider so you can't use unlocked phones on their network.

You can find someone to flash it to Metro though.
