Computerworld is reporting that our friends in the UK have been frustrated by the iPhone 3G launch. It would seem that while the iPhone 3G is for sale in Apple Stores, the activation process isn't working smoothly (sound familiar?). Why is that, you ask? Because O2, that's the UK wireless company that has the iPhone, uses an activation system that only works with IE. Apple had to install Fusion on the Macs in the UK Apple Stores in order to activate iPhones on the spot, and it seems that the system isn't working as smoothly as many would like.
