Dev site has the build number at 11D167 and available for download. When GM or final step is released, I tend to full restore to wipe any gremlins from the beta incrementals. In AI's defense, beta testers may not be their target audience.Edit: pipped by Damn_Its_Hot [sic].
I had one device that complained that it couldn't reach iTunes to wifi sync after the update; something I never saw in incremental 7.1 beta updates. I gonna check it and see if that resulted in disabling wifi sync.
