I don't know why they said that. I still can run http://code.google.com/p/pjs4ipad/ on an iPad 1 with wi-fi shut off with 4.3 (8F190). It works after a shutdown, power-up cycle too.

It's not just the Register, Ars http://arstechnica.com/apple/news/2011/03/confirmed-some-web... makes the same claim, but it works on my desk ;)
