Samsung has the Tango update but AT&T is not pushing it
Although AT&T itself is not pushing out any Tango-8773 updates for its current Windows Phones, the OEMs evidently have it on tap, or at least Samsung does.
We’ve had isolated reports that the Focus S was getting two OS updates (some are reporting new firmware, we’re still at 2188.8.131.52). However, whenever George Ponder or I would plug in our Focus S devices, it was always reported back to us that we had the latest update (7740).
The trick is to rig the system—basically use the same trick many of you did for Mango where you put your phone into Airplane mode (disable all radios), plug into Zune and check for an update. You then navigate away and go back to “Check for update” but as soon as it starts to look (about 2 seconds) you kill your internet on your PC. Now you wait about 30 seconds and an update will be shown. For more info on how that works, read our tutorial here.
You need to do that at least twice—once for 8112 and again for 8773 (Tango)—but yes, it does work and it’s officially from Samsung. We manually installed 8107 back in the day, so our phone was already on that OS version. The majority of you will need to upgrade to 8107, then presumably it will go to 8112 or 8773.

So why is this happening? We can only speculate that Samsung has delivered the update to AT&T but the carrier is either holding it, still evaluating it, not releasing it or maybe they’re waiting on HTC and Nokia to do a universal roll out. Honestly, your guess is as good as ours.
We also have heard this works for the Focus Flash and possibly the Focus 2 (we manually installed Tango on our Focus 2 so can’t really verify). In other words, for all of you Samsung users who are on AT&T (and even non-branded versions), feel free to try this method to grab some updates.
We’ll keep you posted if anything official happens in the meantime.
