Can you jailbreak a verizon iphone 4?

If so… What is jailbreaking will it be unlock to use at tmobilw… Thanks

Yes.

I have your exact problem. I got a Verizon iPhone 4 and right now I'm using it as a iPod. I was unable to unlock it cause it doesn't have a sim slot, I was planning just to put my SIM card in the phone but the Verizon iPhone 4 doesn't work like that. Apparently there's no possibility to use the iPhone 4 from Verizon on t-mobile. What I'm doing is just selling the iPhone and buy one from t-mobile.
