I tried unlocking my iPhone with Sprint but they told me that the phone has to be on my account for at least 90 days before they can unlock it. I haven't reached 90 days yet (I'll actually reach it on Dec 31st) so they said to call back then and they'll unlock it.
In the meantime whatsapp doesn't require a cellular network. It works fine over wi-fi, so it's possible to chat at home or wherever there's an internet hotspot.
