iPhone accessory maker mophie has revealed some details on the restrictions of Apple’s Lightning accessory program. Apple has made it more difficult for third-party manufacturers to produce Lightning accessories outside of Apple’s program.
Good news -- the new Verizon iPhone friendly Apple bumpers now fit 3rd-pa
One of my biggest gripes with Apple's bumpers is that the charge port only fit Apple chargers. If you use any third party sync cables, chargers, or battery packs they would never fit. I have a Griffin Power Jolt battery pack, a Griffin car charger, and several retractable chargers lurking around the house. It always made me angry when I'd have to take off the bumper to use any of these.
