Apple’s Lightning to USB connector has ostensibly been about connecting your iPad to a camera to import images directly to your tablet.
Now, with iOS 9.2, it looks like the same adapter can be used on your iPhone to get photos onto your smaller-screened device.
There’s even some evidence that the Lightning to USB adapter works to connect other USB peripherals, like MIDI keyboards or USB-powered microphones. If you’re a musician on the road without access to your iPad, this might be your new best solution.
