It has now been removed from LinkedIn but a similar listing without a mention of the X-Phone has also been posted on Motorola's own job board.
When Google acquired Motorola Mobility in August 2011, everyone including tech pundits and analysts started expecting news of a new device jointly developed by the two companies. In December, the Wall Street Journal reported that Motorola and Google were in fact working on a device codenamed the 'X-Phone', citing people familiar with the development. A few days back, DroidForums, also confirmed the presence of the X-phone, and said that it would be the first device to come with the next build of Android, Key Lime Pie, and could debut at the Google I/O event scheduled to take place in May in San Francisco.
It would be interesting to see whether the X-Phone turns out to be the first flagship Nexus device made from the collaborative efforts of Google and Motorola.
