Apple will also be starting an aggressive campaign this fall to get all of the after-market cables (lightning, etc) out of people's hands.
The way it'll work is if you have an after-market cable for your iPhone, iPad or iPod, you'll take the cable to an Apple store and trade it for an authorized Apple cable. There will be some cost as well.
After-market cable + $10 or $15 = brand new Apple authorized cable.
One of the features of the new IOS7 will have a warning that pops up, if you use an after-market cable. Your phone will probably still charge or transfer data, but the majority of people will freak out and be looking for an authorized cable.
So make sure that you if you are buying an after-market cable, it's labeled with this:

If you've been using the beta version of IOS7, then you've probably already seen what I am talking about.
