In addition to this post I've a new problem installing my app on my iOS 7.1.1 device over-the-air. I'm getting this error in xcode organizer:
itunesstored[102] <Warning>: Could not load download manifest with underlying error: Error Domain=SSErrorDomain Code=2 "Verbindung mit iTunes Store nicht möglich" UserInfo=0x16ec5030 {NSLocalizedDescription=Verbindung mit iTunes Store nicht möglich}
Could it be a problem with the self signed certificate in general?
