Virgin Mobile called yesterday, trying to get my dad to upgrade. They advised they'd be stocking the iPhone from September, so looks like additional UK carries coming with the 5S
I rang up and they said that the iPhone will be out end of July, beginning of August but obviously not. So i rang again and they said they are in talks with Apple and it would be released before Christmas. So by your answer does this mean that the iPhone will be available to buy in the UK in September on Virgin Mobile?
