Since this whole "update" started, I've been watching and waiting for Samsung to push out the corrected version. Well this morning, I saw and downloaded it. The update is running now...VERY SLOWLY - currently at 51%. I plugged it into the charger and am going to just let it run. I'll let you know what happens!
UPDATE: Well, it took a long time but the update finally completed and the Tab rebooted (again, it took several minutes). But, it reported that the update was complete and finally gave me a message about running non tablet apps, etc. It's now showing Build Number: HTJ85B.UEKMM P7510UEKMM.
Everything looks to be working properly (including WiFi). I'll report back if I see any problems.
