Glad you are OK. But I gotta ask, you still kept the cord?
At this point I don’t know what they’ve done with the cord. If it were me I would have sent it and the packaging off for testing and gone and bought the real-deal iPhone cord. BUT..if it were me in the first place, I would’ve never bought a cord that was “compatible” or cheaper or whatever; I only buy THE cord for my particular phone, mainly because of the issue with lousy data and charging transmission rates.
