I simply installed Beautiful Widgets and used the airplane mode toggle widget to turn it on and then the wifi toggle widget to turn wifi back on. You will now have the phone, oops, I mean tablet with the phone radios off and wifi on. I could be crazy but it seems to have improved performance and battery life since I did this yesterday. It's funny because an hour after I got this tablet I wanted to return it. The more I have customized it the happier I am with the purchase.
