It would be the first smartphone developed since the acquisition of Motorola Mobility. So many rumors have circulated about this mobile that would change the face of the industry. The high-tech enthusiasts were waiting for the powerful new camera _a ceramic design_ that this mobile "had to offer" ...
Motorola will take care of the development of this new Smartphone while Google would prefer to focus on the 5th generation Nexus model.
Therefore the Google XPhone does not exist anymore, and will appear under the name Motorola XT1058.
And the only way to confirm this news is to wait for the Google I/O, that starts tomorrow to see if the XPhone will be absent.
