I trusted third party cables with the 30 pin standard because the 30 pin standard didn't have any smarts in the cable. The 30 pin connector had pins such as GND, +5V, USB + and -, analog audio L and R, etc. Even the most incompetent company in the world would have a hard time ****ing up a cable.
But with the new Lightning standard I'm going to have a hard time trusting third party cables. An implementation error could mean a fried phone or unreliable operation. It'll be interesting to hear reports from those braver than I trying this stuff on their phones.
Maybe in a year or so when third party accessories are perfected I'll consider it. But definitely not now.
