Google has dropped Bluetooth and the GTalkService instant messaging APIs from the set of tools for Android 1.0, but says that handsets using the Android OS will work with other Bluetooth devices such as headsets. According to a post on the official Android developer blog, Google dropped the Bluetooth API from the mobile OS because 'we plain ran out of time.' The GTalkService API was removed because of security concerns that included the possibility of applications revealing more details about users than they might want to let out, such as their real names and e-mail addresses.
