Griffin have come to the rescue of all iPhone 5 and iPad mini customers, where they're the first company to offer third-party Lightning cables. Until Griffin, you've only been able to buy the charge & sync cables from Apple direct.
Griffin are offering up the cables in four different lengths, 2-foot, 3-foot (coiled), 4-foot (coiled) and a 9.7-foot cable, too. Prices are set at $16.99, $18.99, $24.99 and $29.99, respectively.
Apple sells a 3.5-foot for $19, so Griffin aren't the savior in terms of pricing - but at least you get the option of choosing different lengths of cable. Griffin's third-party Lightning cables begin shipping in the first week of December.
