Hah. There isn't enough power in USB, even from the iPad charger, to cause that to happen.
That was likely a failure in the phone, which heated up and damaged the connector plug.
Yes...clearly I'm saying that if you buy a cable from that site it will likely cause your phone to catch fire and then call them reputable. Want to try that again?
perhaps you mean disreputable? why would i call them reputable after they set my phone on fire?
