What do I need to do to my iphone before I can sell it?

At the very least, remove your iCloud account.
What I recommend doing is to put the iPhone in DFU mode and restore it in iTunes. This will erase everything off of the phone and re-install iOS.

Also, don't forget to cancel or remove the iPhone from your carrier.

  • What do i need to know before buying iphone? My plan was to buy a good working at&t iphone 4s then buy a straight talk sim card and have the iphone running off of straight talk but AT&T towers. What do i need/ask about the phone before buying? Also, any other useful info i should know would be great too. Also which sim card would i need for the 4s, AT&T Compatible Micro SIM Card - AT&T Compatible SIM Card
  • Should I take my sim card out before I sell my iphone? I just bought out my contract from my phone carrier and got the phone unlocked, and now I want to sell it. So should I take the sim card out when I sell it or leave it in?
  • Should i replace the back of my iPhone 4 before i sell it? It cracked last year, but I just put a screen protector over it and continued using it. Now my contract is up, and I'm selling it&getting the iPhone 5. Should I replace the back glass (since its easy to replace) before selling it, or would that cost more? Which would be cheaper?
  • Is it worth replacing my cracked iphone back before i sell it? I have just got the iphone 5 and i want to sell my iphone 4 to mobile exchange they offered around £130 for it in working condition but when i emailed and said it has a small crack on the back they said the price could go down to £46 depending on how bad, but i need to send it off for them to asses. My question is, i can get the back repaired for £15 and then send it off, but will this be cheaper then sending it with the damage? Anyone had the same problem? Cheers!
