The new Apple iPhone has sold out in the UK on the first day of customers being able to place orders.
The day hasn't been without controversy however. Existing iPhone customers who registered their interest for the 3G iPhone weeks ago received text messages this morning telling them they could complete their upgrade request online only to be faced with a website that at best allowed them to complete the first stage (of about 5) of the order.
As the day progressed it became increasingly apparent that O2 were prioritising new customers (makes business sense I suppose) and by mid-afternoon there were no more orders been taken with only a handful of existing customers managing to submit an upgrade request.
It is unclear whether or not existing customers with an iPhone can upgrade in-store on Friday with O2 customer services saying that people can - and store managers saying they can't!
