The Android 2.2 rollout has finally begun, starting with Google's flagship phone, the Nexus One.
Android 2.2, codename "FroYo," was revealed last month at the Google I/O conference in San Francisco. It was a major leap forward for the open-source OS, featuring not only major speed upgrades, but Wi-Fi hotspot and tethering functionality, cloud-to-device integrations and Adobe Flash 10.1.
While the newest version of the Google-build OS has been available for a short while now, today marks the official rollout of Android 2.2 to the masses. Most Nexus One owners can expect an over-the-air update sometime later today.
