I've read through old messages and just want to make sure I have this right. I have an iPhone 4S that I want to sell. Here is what I think I need to do: 1. Backup old phone, restore new phone from backup 2. Erase all content and settings on old phone 3. Remove sim card from old phone 4. Profit Now a few questions: * Are the above steps enough to ensure my iMessages don't go to the old phone after it's re-activated? I'm pretty sure it is, just want to double-check. * After #2 above, I see my old iPhone still shows up in Find my iPhone (though it shows as offline). I know I can just remove it from Find my iPhone. But the fact that it shows there does that mean I forgot a step? * It's my understanding I cannot unlock the device until the contract period is over (in 12 months). So I think I should tell prospective buyers that they'll need to use AT&T at least for next 12 months. After that, they can unlock it. Or do I have to unlock it for them at the end of the contract? When I sold previous iPhone, buyer contacted me a year later and asked if I could unlock it because he needed proof of purchase in order to unlock. So I think it would be nice if I provided a way for the buyer to contact me in the future if he/she wants to unlock it in the future. Or is there another way? * Anything else to consider before selling to ensure no privacy or identity issues, etc.?
