A few weeks ago, we told you about a foursquare application developer that discovered traces of webOS 2.0 in their application logs. While the information would have been very hard to fake, it would have been technically feasible due to the fact that foursquare's API is open source. Today, PreCentral is reporting that a closed-source game titled Cloud Hopper has discovered traces of webOS 2.0 in their logs, along with a device that has a screen resolution of 640 x 960; the same resolution as the iPhone 4's Retina display. Whether this device is a prototype of the fabled HP webOS tablet or — fingers crossed — Palm's next webOS smartphone, no one knows. It is nice to finally get a few snippets of information (as small as they are) to let us know that webOS hardware development is marching along… even if it is very slowly.
