The news comes following a story by Spong, which suggested that a patent had been registered for a new Sony Ericsson mobile phone which features a moveable screen that swivels 90-degrees into widecreen mode, and which features a button layout similar to that of the PSP.

However, speaking exclusively to MCV, David Reeves has dismissed the suggestion that a PSP phone is on the cards.

“I know the head of Sony Ericsson very well,” he said. “He has a Walkman phone and a Cybershot phone available, but I know nothing about a PSP phone.

"I haven’t heard anything about it at all – and I would know. They wouldn’t develop it without our knowledge.”
