We know many readers are disappointed that the rumoured Feb 7th Windows Phone 7 update has not materialized, but then we know already that this phone update needs to be preceded by a Zune desktop update, to enable backup functionality.
Now the Zune software is reporting an update being pushed out for the software, and official Zune support is refusing to comment on its purpose.
The version number of the software remains the same at 4.7.1404.0, so it is far from clear what is changed by the download, and a cursory look at the software does not reveal any new backup options.
Hopefully the update is more than bugfixes, but laying the ground work for the much anticipated Windows phone 7 refresh.
Update: According to Johan Peeters, a file from the update (ZuneWmdu.dll) when peered at (just using wordpad even) reveals a connection with phone firmware updating:
Content of updated zune DLLs:CWmduFirmwareDeviceAccess::GetDeviceInfo CWmduFirmwareDeviceAccess::SendFirmwareObject and other things
Update 2:The dll also reports a new build number â€“ 1407.
Update 3: From Microsoftâ€™s support site:
You will have to update the Windows Mobile Device Updater (ZuneWmdu.dll) component of the Zune software to version 4.7.1407.0 or later versions. This software update is intended for use with Zune 4.7 software and is covered by the terms in the Zune 4.7 End User License Agreement (EULA). By downloading this update you agree to the terms of the accompanying Zune 4.7 EULA.
So maybe not the 7th but soon?
Thanks David and Chiefy27 for the tip.
