I am currently downloading the new firmware version for the K850. This has been said to be released in a couple of areas and now the Nordic version has been released as well. More updates once the update has completed. Maybe this means there’s a new one out for W910 as well – I’ll have to check!
Update! There’s a new firmware out for W910, too! Am currently downloading this now. Nothing seems to have changed in the K850 firmware, though 😦 The K850 firmware version is R1CA037, and the W910 is R1CA039.
