So, if we're reading that correctly, the iPhone you purchase and activate will be unlocked. Then, a SIM lock will be "pushed" to your device. But, if you've been a good, policy-abiding customer, your iPhone can then be unlocked manually by Sprint. Who knows what'll happen if you buy your phone and flee to a non-extradition country before Sprint comes knocking at the door, shackles in hand. Will you be left to live in peace with your newly-acquired international Micro SIM? Will you need to plead your case before a tribunal of mobile carrier overlords? Only time will tell, we suppose, or perhaps further clarification from Sprint. Jump past the break for the complete announcement.
"Sprint's policy is to have the iPhone 4S SIM locked to our network domestically and internationally. At launch, the International SIM will be unlocked. We do expect a SIM lock to be pushed to the devices shortly after launch. We will then allow existing customers in good standing to unlock the SIM for international use if needed in the future."
