The authenticator chips in Apple's new Lightning connectors put a stop to unauthorised third-party accessories, at least for a little while. In the meantime, authorised third-party accessories are on the way. The first pair are a car charge and a dock from Belkin.
The car charger is pretty run of the mill. One end plugs into your cigarette lighter "power outlet" and the other one goes into your iDevice's lightning adapter. Simple as that. No holder, no dock, just charging. That'll run you about £25. The other — stranger — accessory is a dock, but catch this: it doesn't actually come with a connector. You can place your iPhone on it, and use it for audio out, but unless you snake your own cable through it, it can't charge. BYOC. That one is £25-odd as well, but it's effectively £50 at least if you count that extra piece you'll have to pick up from Apple.
You can registered to be notified about UK availability of both of them now, if you're desperate, and are due to ship mid-November in the Americas at least. The car charger's fine, but hopefully adapter-less docks aren't about to become a trend. If so, you better hope those working knock-off Lightning cables start rolling out, and fast.
