There are lots of iPhone accessories that can be controlled with different apps. But what will you do if your iPhone doesn’t have the app required by the corresponding accessories?
Now you’ll never have this problem because iPhone will now prompt you to install the  corresponding  app.

Apple is now allowing “Made For iPod” and “Works With iPhone” certified developers to include automatic application download prompts when connecting to app-supported accessories.

Once you click on the yes option in the prompt, you will be redirected to the all new “For This Accessory” page in the App Store. From there you can easily select the app required by the corresponding accessories. This is indeed a great feature introduced in iPhone.
