My iPhone 6 just took a dunk in my toilet this morning, and to add insult to injury, yes, there was a fresh log in there too. FML. The phone has been doing fine all day, except that I just noticed it won't charge. I'm going to open it up tonight and do a thorough investigation and cleaning, but I'm also preparing for the worst and fully expect to have to replace it. My question is simple: Can I buy a phone with a bad ESN, and just swap out the motherboard and SIM? Why? I have a 128gb phone, and I need the cheapest option available, but most importantly, I don't want to lose the last 6 months of photos/vids that I haven't backed up yet. I've already done a motherboard swap before with my previous iPhone 5 that had several F'd up parts (but not water damaged). However, I don't recall the specific circumstances or the status of the donor phone (i.e. whether it was bad ESN or not).
