iOS 7: Disable message "This cable or accessory is not certified and may not work reliably with this iPhone"?
The expected behavior when you see this message is to simply contact the vendor of the cable or charger and verify that your are in fact safe to charge an iPhone.

I would hate to tell people to disregard a message that could have safety implications. Granted, not all third party cables and/or chargers are faulty, but what if this were a warning that could get you to seek assistance from Apple or the vendor and ensure that a sub-standard part isn't being used to charge your device.

Given some of the horribly unsafe chargers that I have personally seen, I don't expect this to be an easy warning to bypass without jailbreaking.
