If you're already using Android 4.0 or iOS 6, you're likely familiar with the option to send a pre-made text reply to incoming calls you can't take. But what if it's your own call that won't go through, at no fault of your own. Apple may have that covered through a patent application that could keep the accusations to a minimum. If flaky reception at the destination prevents your call from connecting, the proposed idea has your iPhone automatically send a text message indicating that you've at least tried to get in touch.
