I paid a lot of money for a few apps that use the headphone jack and will not work with any kind of blue tooth. Those apps would be useless with a 7 phone.

Sorry,

No sale.

Really curious - which Apps rely on the Headphone jack? And how would they be unrecovered by changing to the Lightning port?

Personally, I can think of only one that might present a problem, and I believe the enclosed, free, Lightning to 3.5mm Headphone jack will circumvent that problem. That single problem would be the SquareD Visa/Mastercard reader. But, as I'm sure that this has been considered, I doubt that whatever problem you imagine will be a problem; is either has been fixed, or will be fixed in an update coming out soon. App developers do not want to lose sales, because Apple made an updated iPhone. As a developer - I know I wouldn't want to lose any sales, so I am certainly going to keep to date on my apps. I would assume they would too.

Wrong. An adapter is supplied free in the iPhone 7 box. Your existing accessories will continue to work with the iPhone 7.

No, they won't. The iPhone 7 still has a 3.5mm jack that works from the Lightning port, and its a free, included adaptor. Your apps will work fine.
