So I've got a question. I recently found an HTC EVO 4G, no ones come to claim it and it's been two weeks. I want to be able to switch out my blackberry to the htc. The thing is, is that if the person who lost it went to Sprint and said it was lost or stolen, Sprint would not be able to switch the phones for me.

What should I do then, unlock the phone or what? I'm on the same service (Sprint) as the HTC.
