So, I've already searched through countless threads about selling an iPhone 4, price points, among other things, but I need some info in this own thread to make sure I'm doing this completely right, so here are my questions and some info: 1. I bought an iPhone 5 a while ago, and has been activated for a while. 2. Do I leave the SIM in or do I take it out? Since my iPhone 5 has already been activated, I would guess that it leaves the SIM useless? Or is this not true? 3. I completely wipe the phones, as in, "Erase All Content & Settings" if I want it to be a completely new phone, correct? 4. If the person I'm selling it too goes to get it activated, they will give him a new SIM, and it will not be connected to me in any way possible, correct? 5. Lastly, what would the selling price be for a fair condition iPhone 4 (scratches along the sides, micro screen scratches, etc.)? I was thinking around $100-$125. Thanks!
