You can use your iPhone or iPad (cellular modes) to provide a personal wifi connection during a power outage. This may come in handy if you can't use your home internet service and you want to connect a laptop or other battery powered device to the Internet via WIFI.
It's very simple to do!
1. Take a selfie by using your earbuds. The + (volume up) on the cord will snap the photo for you.
2. You can add more icons to your iPad dock. You can even add a folder with lots of apps to the dock. Just drag and swipe the icons or folder you want to the dock.
