I purchased the Otterbox Armor for my iPhone 5 on Friday, 2/22, from a local AT&T store. Later that night, I discovered the problem with the 30pin to lightning adapter (0.2m). I then boxed it back up and returned it to the AT&T store the next day. I found this thread and wished I had read it prior to my trip to AT&T.
I decided to send a Tweet to Otterbox about the 30pin to lightning adapter cable not fitting. Otterbox Customer Service tweeted back, "Sorry to hear that. Some adapters do fit." Well, I wrote back, "Really? Name one adapter, sold by Apple, that fits, other than the standard cable that comes with the phone." They responded last night with the following tweet, "Unfortunately, we can't advise on 3rd party products but there are forums that have recommendations."
Considering that there aren't many Apple approved lightning adapters out there besides Apple's adapters, I wonder what other "3rd party products" Otterbox is referring to?
So, my iPhone is back in its Defender case. I shall continue my quest for a highly protective case for my iPhone 5 that is also waterproof.
I think OtterBox engineers made a huge mistake here. If you notice, the width of the hole for the lightning port is too narrow for the adapter, but the adapter fits just fine in the hole for the headphone jack. However, it's way too big for the headphone jack and the width of the lightning port hole is just right for the headphone jack. In other words, it looks like they exchanged the width of the holes. If the holes had the widths reversed, the lightning adapter would work perfectly. As far I I can see, there is no functional reason why the headphone hole is as wide as it is.
