Those waiting in line to get their hands on the iPhone 3G, which launched in the UK this morning, report that the queues are moving, but only just.

Macworld editor Mark Hattersley has been waiting outside the O2 store on Oxford Street in London since 7.45am, and officials there expect to handle 15 customers per hour. He's been told he faces a wait until around 2pm. Some reports suggest every single person in the queue is having to pass a credit check, regardless of whether they already have a contract with O2.

And owners of the first-generation iPhone who hoped to get fast-tracked have been disappointed. iPhone 3Gs are being sold on a first-come, first-served basis.
