We all knew this day would come. It's hardly a tragedy, but some globe-trotting types out there might be a little annoyed. Starting today Sprint is pushing a SIM lock to all iPhone 4Ss on its network. As you may remember, the first batch of Apple handsets sold on bee-hued carrier were unlocked, but the company was perfectly clear that would be changing. A Sprint spokesperson told us this doesn't constitute a change in policy, "think of it as getting the device in compliance." Subscribers in "good standing" for at least 90 days can always call customer service and request the device be unlocked (again). Check out the full explanation of the locking/unlocking policy after the break.
