Here’s the best tip ever for when your home button is stuffed on your iPhone (until you can get around to fixing it).
Go to settings, general, accessibility, and then turn on assistive touch.
This will allow an icon to appear in the top left corner of the screen that, when pressed, expands and gives you the ability to activate the home button on the screen.
Very clever. A nice temporary solution until that $3 button and pentalobe screw driver arrive from eBay.
