Is iphone 6 only available in mobile stores on sep.19?

I know it's a dumb question since it said in the article it will be available on the 19th but just want to make sure.

Yes, and in limited supply I'm sure. They always wait almost 2 weeks after the keynote to put it in the store. Just the way Apple does it. Online preorder starts this Friday I think. That'll take a few days for delivery if orders are tight too. Best luck.

Yes. September 19th

If they have them in stock. Many will pre-order.
