Do sprint phones work with virgin mobile?

Nope, you can't

Yes you can they both are cdma. Some people have less knowledge then they say they do but anyway.... Boost virgin and Sprint are all running cdma. But I have actually activated a sprint phone to virgin mobile for a friend of mine. Everything worked right after activating which actually suprised me but I still had to flash virgin mobile firmware on it which makes it a virgin mobile phone. I think they need to ask questions before they let people tell you something that's just a down right wrong answer. With flashing and odin and mobile odin and a just a lunix emulator you can do a lot.
