Unfortunately, Samsung's own actions have led to the troubles. It seems that because Samsung was quick to appeal the original ban on the Galaxy Tab 10.1, that appeals process keeps Judge Koh from being able to lift the ban, even though the jury found that Samsung wasn't infringing on Apple patents with its tablets. According to Koh, "Samsung’s pending appeal of the June 26 Preliminary Injunction deprives the Court of jurisdiction to dissolve the injunction until and unless the Federal Circuit returns jurisdiction to this Court."
The tablet can still be purchased via T-Mobile or Best Buy, but can't be sold by Samsung. Of course, it may not matter all that much anyway since the Galaxy Note 10.1 has essentially replaced the Tab 10.1 in Samsung's tablet lineup.
