Can you unlock the Sprint iPhone to work on T-Mobile?

I want to buy this sprint one on ebay, but can it be unlocked?

I don't think so every carrier goes with every company: s

It is not possible cos sprint is cdma while tmobile is gsm.ingnore the scammer kaar.

You can definitely unlock an iPhone locked to Sprint network. You can unlock it safer and easier using remote unlocking service. You can get the remote unlocking service for a Sprint network locked iPhone from http://www.simpleunlocking.com/apple/rs16wp8/ at low cost. This method of unlocking doesn't require a jailbreak too. Once it is unlocked you can use it with any Non US GSM network. You can use it with any T-Mobile network other than US T-mobile. Or it would be better for you to buy an AT&T network locked iPhone and unlock it tom use with US T-Mobile network itself.
