The long awaited (or dreaded for some) TouchWiz UX update is coming to NYC on August 3rd. NYC was also the first to buy the Galaxy Tab 10.1. You have to literally go in to the Samsung Experience center in New York City to grab the update. They will manually sideload the update on to anybody’s Galaxy Tab 10.1 that wants it. The doors open to the public at 1:00 PM.
Earlier in the day Samsung shows off all the features of TouchWiz UX to the media. You can read about what the update brings here. An over the air update will be rolled out to everybody else soon. You do not have to wait though, because XDA has a leaked version that you can install if you so choose.
