I can tell Apple is taking the new opportunity of selling iPhones in China really seriously. This update just turned up on my iPhone, and I don’t even live in China. Presumably every iPhone5 user in the world has to install an update just so they can fix a provisioning problem with iPhones sold in China. ‘Provisioning’ is all about activating a new phone on to a phone network, so it looks like they’ve had some issues with Chinese customers unable to use their shiny new smartphones.
