Vodafone Australia has posted on their blog that the PR2.0 Nokia Amber update is currently in testing for the Nokia Lumia 820, and that testing will soon begin for the Nokia Lumia 720.
An update is also in testing for the HTC 8X.
The testing phase tends to last less than 2 weeks, suggesting we can expect to see the OS roll out at the end of July or early in August, at least on this carrier.
The Nokia Amber GDR2 update brings back support for the FM radio, brings Datasense to all handsets, an Always ON Clock, Double Tap to Wake , Nokia Smart Camera App , CalDav & CardDav support , and a host of other features, including Bluetooth 4.0 support for the Nokia Lumia 720.
