If you’re like me. and have tried the Windows My Phone service out a little bit, but decided that it’s still a bit half baked, undercooked, to be a viable stand alone syncing service for your WinMo phone you probably didn’t set it to update automatically. Besides the fact that you are going to need an unlimited data plan, to support this function, there might be a few tricks that you are missing if you don’t manually sync regularly. One feature that a lot of people have missed is the fact that any updates to the phone side app, are notified, applied at the end of the syncing process.
Now this is not insider info, I noted a tweet this afternoon from @MSMyPhone, dropped the information, so I manually synced when I got home and Viola, an update to be sure. Not sure what it fixes exactly, and the only thing I could find about it at the MyPhone Blog or user forum was this mention,
The update fixes an issue with regards to syncing documents to the device.
Please install the update and everything would work fine.
