Do not -- repeat -- do NOT put WD-40 or any such substance in your iPhone or iPad -- it won't permenantly fix your Home button and may, in fact, damage it far worse. The idea that repeatedly squirting WD-40 into your iPhone or iPad Home button could fix responsiveness began floating around the internet last month and has gotten some attention -- that needs to be stopped immediately. Keep in mind we're huge fans of DIY repair here at iMore. We have a weekly column focused on DIY repair. But putting WD-40 is not DIY repair. It's dangerous, particularly for iPhones and iPads that are built with moving, plastic parts.
