Come one, come all [Google I/O attendees] - the official I/O app is now available in the Play Store. It includes maps, event schedules, the conference agenda, and detailed information about all sorts of devvy stuff. Oh, and this year you can play back various "I/O Live" talks and events straight to your 3.0+ tablet. Awesome. In addition, Google will be open sourcing the whole app once I/O has ended.
Another new feature comes in the form of Android Beam support for 4.0+ devices, allowing you to "bump" session details between two NFC-enabled Android 4.0 phones.
Head over to the Play Store to pick it up now.
