Can you fully flash a iPhone 4 or iPhone 5 to metro?

No. Simple.

One way is to jailbreak and the get Dreamboard, and then get a metro Dreamboard theme.

There may be a custom firmware you can get to obtain Metro, but if there's, it's quite hidden.

I heard you can full flash an iPhone 4, by editing the prls. But i'm not positive, haven't looked to much into it. Not sure on the iPhone 5 yet.

Of course it needs to be either Sprint or Verizon version
