Added a lock/power/sleep button and two volume buttons. Also I added some trim. The new button opens a text message or an email. You can configure it in the system settings. Comes with Android 3.1. It will not come with a new pre-installed Android OS until Android 3.3 comes out. It will never have pre-installed Android 3.2, 3.4, 3.6, 3.8, 4.0, 4.2, 4.4, etc. etc. etc.
