Here is an interesting rumour: The very first Google Android device, the T-Mobile G1, could be in for an update to Google Android 2.0 or 2.0.1, according to AndroidSPIN.com.
The update will be at least Android 2.0 but more likely Android 2.0.1 as both versions have already been prepared as OTA updates. An anonymous source of ours has confirmed that both the Android 2.0 and the Android 2.0.1 are in the hands of some very fortunate people.
The T-Mobile G1 was launched with Google Android 1.0 but has since received a number of updates, the latest being Android 1.6 and Google Maps Navigation.
