Some people have been queuing for days outside Apple and AT&T stores across the US to ensure they get hold of one of the devices.
Hundreds more are expected to start queuing during the day because stores will not start selling the iPhone until 1800 local time (2300 BST).
Apple said buyers visiting its stores would not be able to walk out with more than two iPhones each. Apple's iPhone makes it to stores (more)
