So I dropped my iPhone in the pool. It doesn't work anymore. Bought a new phone and all is great. I recently saw on eBay people selling they're broken water damaged iPhones and it caught my eye. One thing that I was wondering though was will the person who buys my phone somehow be able to access everything that was on there? And also do I need to for some reason take out the sim card? Idk if that really matters or not. So overall how do I get this stuff off of there or should I not even be concerned?
