Kelsea Weber is apologetic for being hard to get ahold of. “We were all busy tearing down the iPhone XS,” she says.

A few minutes’ conversation with Kelsea is enough to convince you that she would be taking apart brand new Apple gear no matter what, but she does it professionally. Weber works for iFixit.com, a website you may have heard of once or twice. It provides repair videos, manuals, and tool kits to more than a hundred million visitors a year.

Or, to put it bluntly: iFixit.com is essentially a clearinghouse for information that some of the big names in consumer electronics would just as soon keep to themselves.
