Do I need to unlock my iPhone before selling it?

I'm breaking my contract with AT&T through Cellbreaker, so I don't believe AT&T is going to willingly unlock my iPhone for me. Is it alright to sell the phone as is, without unlocking it? Or is there a way to unlock it (if it means selling it for more money)?

If you unlock the phone, you'll have more resale value. As AT&T is not going to unlock the phone, get it unlocked from third-party. If you need help with getting the iPhone factory unlocked, mail me for more info.

You can sell an AT&T locked iPhone no problem. Just make sure it is advertised as such.

  • Which is better: selling on amazon or selling on ebay? I have an individual seller account and I've noticed that my products sell much faster or ebay. However, I sold two iphones. My final sale fee $1100. However, ebay charged me a final sale fee of $135 Then I was charged $40 by paypal Then I paid $60 total to ship both items. On my amazon account I sold 1 phone. The phone cost $180 Amazon took out $30 Shipping cost $10 So I made $140
  • What to do with iphone before selling? I want to sell my old iphone but I'm not sure what to do with it first. I've reset the whole device to factory settings, but is that all I need to do? I've already got a new phone with my number. I'm just curious as to what will happen when the new owner turns it on. Will they just have to set up their phone number to the phone? I hope I will not still be paying for the phones data when they turn it on… Any advice?
