Not sure about doing it that way, but you can order unlocked phones directly from apple.com. I just ordered 2 iPhone 4S and both are unlocked.

Unlocking the SIM is useless with a CDMA carrier. Also Virgin? Mobile, along woith Boost Mobile are both the prepaid part of Sprint.

There's no need to do what you say. The unactivated price for the Sprint phone is $2500 higher than the VM phone. $699 vs. $449
