Can you connect an iPhone 4S on metro PCS 4G data plan?

So I have a phone on my metro account a 4G phone and I just got a 4S Verizon, all I wanted to know if it can be possible for them to connect it with there 4G network

Yes its possible just take it to metro and ask them if they can flash it if they can't you can usually find someone to do off craigslist or in some cell phone stores (not branded stores).
