iOS 7 beta: Testers warned when using uncertified Lightning cables

Developers testing Apple's first beta of iOS 7 will receive a warning prompt on the screen when using an unauthorized Lightning cable to charge or sync.

Because the software is in beta and is only available to developers to test, it's possible that the warning could be changed or completely removed by the time iOS 7 ships to the public. But at the moment, the operating system presents a prompt that reads:

"This cable or accessory is not certified and may not work reliably with this iPhone."

Testers can simply dismiss the warning, and the Lightning cable, if functional, will still work as expected.
