Less than a month ago the Google Sync app got an update and again today its been freshened up. The new version is 0.7.3, and yet again no changelog is available. We can assume there wasn't much added and the update most likely just fixed up a few bugs. I really wish Google would get to it and put out some decent updates for both the Gmail app and Google Voice among others, but it seems like wishful thinking on my part. Regardless, you can grab the update from your device by heading to m.google.com/sync.
