Bought the phone on Friday and it was running 1.6, been looking how to upgrade to 2.1 myself over the weekend and today the official update was made available. Thanks TNZ.
Downloading now and look forward to the extended battery life. Currently lasting about 6 hours! But mostly because it my first Android device and I am still learning, corporate email was the first to be tuned.
Will post a further update if it was successful or if I bricked it! :)
