Samsung dropped word tonight that it's pulled the Android 3.2 update being pushed out to the Galaxy Tab 10.1 after a number of users reported problems, including Wifi connections being broken. Here's Samsung's response:
“Samsung is aware of an issue that some Galaxy Tab 10.1 customers have experienced with today’s software update. We are working on a resolution and will provide more information shortly. In the interim we have chosen to discontinue availability of the update.”
Hopefully we'll see a fix -- and a fix for those who already applied the update -- shortly.
