Can a verizon iPhone 4 work on tmobile?

I recently switched from Verizon to Tmobile but had my GS3 stolen. I still have my iPhone 4 from Verizon but will it work on Tmobiles network?

You have to have your gsm unlocked so any carrier can provide there service if you don't have it you can find someone like in a phone store to do it for like 10 or 15 dollars anything higher is a rip off

NO, it won't work, not now, not ever. The Verizon iPhone 4 does NOT have a SIM card slot, which is needed to use it on T-Mobile's network.

It will not work… It is true Verizon's Iphone is global ready. BUT… Apple blocks ATT and Tmobile and all USA GSM carriers on the Sprint and Verizon Iphones. There's no hack for it. This is why you never see a Verizon or Sprint Iphone on ATT or Tmobile or any GSM carrier in the USA. It will only work with other country SIM cards. But never on GSM in the USA
