Why can't text via wifi in airplane mode?
After iOS 6.01 I still cannot send text messages over wifi while in airplane mode and I definitely could with iOS 5.x. Even with cellular data turned off, when I try to text it tells me I must disable airplane mode to text. Needless to say, since I'm flying, I shouldn't do that. Is this a bug, or I'd there some new, hidden parameter that needs to be set?
iPhone 4S, iOS 6.0.1
