What's the best way to get Apple to do a non-warranty repair on your bricked or broken iPhone or iPad? Simple: tell the truth.
I have seen all kinds of schemes cooked up by people who have done something ill-advised to their devices. They have a strategy. They know how to fool the liquid sensors. They have a story for the dent they couldn't pound out. They play innocent when their product is mysteriously bricked. They have a plan for every contingency.
When all else fails, they make noise, complain to the manager, write angry letters to SJ and the media. Finally, they post on internet forums and try to win in the court of public opinion. Well, I'm here to tell you, there is a better way.
