A tweet from Kevin Marshall revealed a picture of an HTC Trophy running a Google+ application that hadn't been seen before.
It seems like the application is authentic, as it comes from a company that has previously created applications for the platform, and everything shown on the screen seems to line up online. In addition to this, the application appears to adhere to the Metro design guidelines.
As, a snoop around done by neowin to check if the shot lines up with real Google Plus images and names, so searched public Google profiles to confirm. "First up, we searched for "Kurt Brockett" who exists, and the profile picture matches up with the picture shown on the device above. In addition, he also happens to be a UX designer. Next up, Steve Holstad who is also listed on the screenshot, also matches up on Google Plus. We were able to find the correct picture, and also discovered that he too is a software engineer at Clarity," said.
