All a sudden, my iPhone 5's lightning cable started warping. Now it's all exposed at the connector area. Oddly, the top part of the cable keeps compressing together, making the situation worse. It's like out of nowhere the sheath came apart and now it only works by touching and moving it. I haven't had this cable 2 years yet (Nov 2012). Meanwhile, I have several 30pin cables that are anywhere from 4 to 8 yrs old and never had a problem with any of them.
Apple must redesign their lightning cables because they should to last for years, like their older cables, and not months.
