If you’ve plugged your Developer Preview Windows Phone Mango beta device into Zune this afternoon, you may have noticed that you’ve got a bunch of updates available. The first one installs the full RTM build 7720 version of Mango, then it will look for and install a “Beta Bundle Cleanup” update which will get your phone back on track for the official updates from your carrier and original equipment manufacturer. After that little update cleans everything up, you might also notice some updates specific to your phone. After a few more minutes, whichever phone you may have been using the beta version of Windows Phone 7.5 on will be totally up to date. Yes, this works on unofficially upgraded beta versions as well!
