A tech enthusiast site called TechHog recently leaked an image of what it says is the upcoming third Nexus-branded smartphone from Google. Though the site’s post has since been pulled, the photo shows a phone with a buttonless design built by HTC and a form factor that slightly resembles that of the iPhone 3GS. If Google wants to ditch the Android menu keys on its next Nexus device — which would presumably run Ice Cream Sandwich, likely eliminating the need for the typical Android menu keys — we’re all for it, but we’re not so sure this particular image is even real. Hit the jump for a zoomed-in portion of the photo that shows a jagged border typically seen when a Photoshopper isn’t careful enough with the clone stamp tool — just one of several problems that leads us to believe the image is not authentic.
