An anonymous reader writes: Google has used the I/O developers conference to launch the latest version of its mobile operating system, Android 2.2, codenamed Froyo. Google claims the operating system will be from two to five times faster thanks to advances made in the compilers and the Dalvik virtual machine it uses, and how it is ported to new processors and platforms. On the enterprise front the new operating system comes with full support for Microsoft Exchange, including access to the global address book and the ability to translate native security features to mobile handsets. APIs have also been added to allow controls such as the automatic wiping of missing handsets and other remote management features. Google is also making its voice translation and search APIs open to developers, and showed off an application developed for the handset that allowed real time translation from English to French.
