Updating simlock error

The region lock is, as we suspected, designed to thwart phone importers who buy phones from one region of the world and then sell them in another.The region lock will, of course, adversely affect individuals who end up trying to activate a locked phone for the first time outside of its home region (they're bound to get sold online anyway), so it's something to be aware of.

As part of what is apparently a new policy for the company, a number of popular Samsung phones will be SIM-locked to the region in which they are sold.

The bit doing the locking lives inside the CSC (Consumer Software Customization) package in an MCC whitelist, specifying which country codes the device can be used in based on what regional software variant it is.
