Using Pillonel’s work and the documentation on their GitHub page as a starting point, Jöbstl’s own customized iPhone X includes a couple of key improvements. To boost the durability of the added USB-C port they created a custom support, partially made of carbon fiber, that helps ensure the connection won’t come loose after repeated uses.

More importantly, one of the best features of modern smartphones is their ability to shrug off a drop in a puddle or an accidental dunking in a toilet. It’s a feature often compromised after a custom modification, but through the gratuitous use of super glue that ends up mostly hidden away inside, Jöbstl’s USB-C iPhone X retains its waterproofing.

To help fund further modding endeavors, Jöbstl plans to put their iPhone X up for auction starting at 12pm EST (17:00 UTC) on January 19, with the link eventually being shared in the description of their YouTube video. Will it end up selling for more than $86,000? Assuming Apple doesn’t reveal a USB-C-equipped iPhone 14 in the next five days, you’re probably going to need deep pockets to win this auction.
