What prepaid services can I bring my Sprint iPhone 4 to?

I want to be able to bring my iPhone 4 to a cheaper prepaid service/plan (similar to virgin mobile, page plus, and metropcs). I don't understand "flashing", nor do I want to pay anyone to "flash" my phone for me, so that's out of the picture. I would love a list of cheap plans that would let me bring my own device that is a Sprint iPhone 4.

That phone is cdma only which means it doesn't have a sim which means it can only be used on sprint unless its flashed to another carrier

If it was ann att iphone easy unlock and many choices of carriers… Sprint not as easy

I'm not sure how this unlock and carrior transfer business works… Is it possible to switch from Sprint to T-mobile? - Would there be any limitations? If so where can I go to have the phone unlocked. Is there any possible free ways of doing it? (like using redsn0w or such software)?
