Sony Ericsson introduced a new phone on Thursday that allows consumers to connect to their PlayStation3 gaming consoles, part of its Christmas line-up and its strongest sign yet of integration with parent Sony Corp. The Aino phone will allow users to manage media stored on their PlayStation3, much like the PSP mobile console and helping position the video-gaming console as a media hub, but will not allow them to play games or access high-definition video. Sony Ericsson has rapidly lost market share in recent quarters as demand for so-called feature phones has suffered during the recession. Market expansion has been seen at the high-end smartphone and low-end emerging-markets extremes.
