One of the major changes in the new iPhone 5 is the new 8 pin “Lighting” cable instead of the 30 pin cable used in all iPhone and iPad devices previously.
Now the general purpose computer that you can make phone calls on (i.e. the iPhone 5) comes with a Lighting cable, but odds are you are going to need at least one spare. No problem if you don’t mind paying Apple $19 for a spare cable. If that is a bit pricy for you, you may have to wait.
According to one cable manufacture that has done a tear down of a Lighting cable, Apple has put an authentication chip in the cable (which is doing D2A conversion as well). So beware of any third party “Lighting compatible” cables for a while. I’m betting this can be cracked, but it may be a few months before its done and third party cables start hitting the market.
If you are laying out the cash for the Darth Vader phone, part with another $19 and get a spare cable. You’ll need it. I’ve been considering a dual 1.0/2.1 amp car charger anyway, so can I could charge both my Nexus 7 and an iPhone at the same time. I could charge my iPhone straight from the car’s USB port, but the Sync system treats its as an MP3 player and tries to index it, which screws with the Bluetooth streaming (are you paying attention Ford?), so it’s easier to use a car charger plugged into a power point (the former cigarette lighter socket). The care would probably do the same thing to the Nexus 7, but I don’t keep much music on that (lots of music on the iPhone anyway).
Ok, back to the cable, you can get a 30 pin to Lighting adapter. Apple sells one for $29. Again, off the bat, I’m not sure I would trust any third party adapter for a while. Not until some early adopters spring for them and start sharing their success/failure rate.
