Coming from iPhone 6, now that I have two days to play with my iPhone 7, I think I like it. I will keep this. This is what I am planning to do 1. Erase all content and settings. 2. Remove SIM 3. Charge it up to 70%, just in case they want to turn it on and test it. 4. Take pictures/videos of phone including packing the phone (burned by eBay couple of times) 5. Wrap the Phone in a bubble and packing it in the box they sent me. What steps are you taking before you send you phone to Verizion?
