In less than a day, Apple's annual Worldwide Developers Conference or WWDC will commence. Of course, that means there's time for a last minute flood of what may or may not be revealed at the event. This latest one is quite some big news for Apple's fresh new mobile payment system. Sources claim Cupertino is ready to announce that Apple Pay will be landing in the UK this summer. While mobile payment in the US isn't exactly new, this is very big news for those across the pond.
