Apple never gave the date as July 11. That is the date the new iPhone comes out. The update will likely be out before that. At the apple store they will tell you early July.
I agree with astrochuck, they never say with that words “July 11th” for app store, they said “early July” the exact date its for the iPhone… I just hopes its July 11th at the most, can’t wait much more! I’m sooo anxious!
