If you've been desperate for new Gmail on your Android, a leaked APK obtained by Android Police -- that may or may not have come from one of those LG E960 Mako (alleged) Nexus phones that it seems everyone has -- is sporting some fresh tweaks. As seen in this demo video, the update adds pinch-to-zoom on individual messages, as well as swipe to delete or archive. The app itself is labeled as version 4.2, and while the APK isn't widely available, the site reports that if it is released you'll need to be rooted and running Android 4.0 or higher to get an early taste of the future.
