I have a sprint iphone and i want it on verizon?

I have a phone that my step dad gavee me (iPhone 4) but its on sprint and I have Verizon… If it matters… Currently I have an HTC thundebolt my thunderbolt has a sim card the iPhone does not… Any help is grately apreciated

You can't get an iPhone 4 from Sprint to Verizon. I think each phone is made for each provider.

While I do hope that my help is greatly appreciated, I don't really know what to tell you other than to contact sprint or Verizon. Hope this helped

I believe they are on the same network.go to there store and see.

I know that you can't do that with t-mobile and at&t because they both suck and have a stupid sim card.
