Nokia seems to be wrapping up testing of their much anticipated firmware update, 12070. The update brings better battery life through better controlled screen-brightness and ~70 mA discharge when idle. In addition, the update tweaks the camera's white balance a little and sound is improved via the bass response.
We can testify that 12070 has nearly tripled our battery life since we forced-upgraded from 11401, making this a worthy and important update for Lumia users.
Those in Singapore seem to be the lucky ones tonight as they are now getting 12070 official through Zune Desktop, making them the first group to get the honors. So if you're in Singapore, y'all need to stop reading this and go get your update as it is totally worth the 15 minutes.
We expect the rest of Lumia 800 users to start to get their updates later on this week. Stay tuned.
Thanks, VoodooKing for the heads up; See XDA forums for further confirmation
