The leaked version (apk) of Google Plus 2.0 for Android reportedly supports both Android Gingerbread and Android Honeycomb OS. Apparently, the new version is designed for the Android 4.0 OS, which in our knowledge, is supported by the unannounced Nexus Prime Android phone. There are no details as to what's new in the leaked release, but something that's utterly obvious is that the version has a revamped UI, and loads of interface improvements.
Google is yet to announce the Android 4.0 OS and the first phone running it (Samsung's Nexus Prime).
