Trusting your survival to one piece of electronics is never a good idea. You have heard of Murphys Law. What about redundancy? If I crash and break the phone I would be stuck without a GPS and a IP68 rated phone. Do you carry a spare phone? I do + a PLB and GPS. The last group ride I went on turned into a monsoon mudfest and more than one phone was damaged by the weather and all of them were in backpacks. So I can drop my $800.00 iPhone in the toilet and it will be just fine? Can I replace the battery in it when out on the trail? There are plenty of phones out there that are not IP68 rated and the uninformed or inexperienced owners will inadvertently destroy their phone because some one told them nothing could go wrong. I am well aware of the technology of today and I have repaired my daughters iPhone several times but anything mounted on a dirt bike is in a hostile environment and I'm not a huge fan of mounting expensive electronics in harms way. That said it's your phone so you can do whatever you want with it. I use a GPS and keep my phone sealed up in my backpack and use my satphone (IP65 rated) to make a call or text or email my GPS position if I need to. Redundancy.
