There’s a subtle defect with 7.0 iMessage for correspondents who have intermittent data service. It used to reply to SMS with SMS, now it persists w/ iMessage if contact has past iMessage use. No fail message but need to manually resend as Text. #t Posted on November 15, 2013 by jgordon From app.net – http://alpha.app.net/johngordon/post/15063243.
