CDMA Unlocking??????
Sprint carries a motorola phone like the V555 to be used for customers that need an international phone. There are special plan requirements to use this phone, but since it's a quadband GSM phone it's an international device.
Here is the only way possible from my knowledge. Activate the Motorola phone on one of Sprint's international plans (no clue what they are and how much, probably expensive). Take the sim card out, and place it into an unlocked GSM phone. And should work (maybe) 😕
Don't know how it's done, but I remember hearing something about a California law passed last year that allows this. Don't know if it impacted Sprint, but it might have.
Something to do with loading the ESN to Sprint's database (don't know how) but then web and certain phone features will not work, unless you have a WM phone and flash over the Sprint ROM onto it. (don't know how either)
Not too common of a question, and is ALWAYS less of a hassle on everybody's part to just get a Sprint phone.
As you realize I don't know much in this department but I would refer you to Mobile-Trojan, I've seen him post about this before.
the short version of the answer is no, there is no way to use anything other than a SPRINT phone on sprint, and each CDMA company is going to be the same, with the exception of cricket in our area. they tend to have good luck flashing sprint phones to cricket, but then they will never work again on sprint.
happy trails
