As for HTC's flagship phone for Sprint, there hasn't yet been an official announcement, but Android Police is reporting that Android 4.1.1 and Sense 4+ are rolling out now. We've had a number of tipsters write in to tell us the same. It sounds like the update isn't being pushed out automatically, but if you go into the settings menu to perform a software update you'll get the second-most recent version of Android on your Evo. It's a nearly 400MB download that requires you to be on Wi-Fi, so make sure your battery has some juice left. If you're using one of these fine Android devices and have been waiting for your first taste of Google Now and Project Butter, your wait is over.
