We have checked with a number of AT&T (T) sources, and so far, the only thing that looks to be showing up is iPhone 5 cases from Speck. No Lightning to USB cables, no Lightning adapters and not even any car chargers. It looks like Apple (AAPL) kept its Lightning charging specification secret, just like rumors suggested. Here are a few different iPhone 5 cases you’ll be able to purchase tomorrow, though we’d courteously ask you to refrain from using a case this time. Please?
