    Froyo is the dessert-themed Android codename for the version 2.2 update of the open source Android mobile operating system. Short for “Frozen Yogurt,” Froyo made its debut in August 2010, adding new features like USB tethering support (for effectively turning a smartphone into a Wi-Fi hotspot), Flash 10.1 support, voice dialing over Bluetooth, the ability to store apps on external memory cards, significant speed improvements and an browser update that adds Google Chrome’s V8 JavaScript engine.

    Froyo follows three earlier updates for Android Cupcake (v1.5), Donut (v1.6) and Eclair (v2) — and has been superseded by more recent Android updates Gingerbread (v2.3), Honeycomb (v3.0) and the upcoming Ice Cream update.
