[Q] Sell Unlocked New In-Box AT&T White S3 for Max $$$

[sonicthoughts]

I just received an AT&T S3 as a free non-commitment temporary phone from AT&T . Turns out I no longer need it and want to sell on Ebay (or other) I assume the phone is carrier locked and see many sales for New in box unlocked phone. I assume that once I turn it on it will deactivate my old SIM and activate new, but I want to keep my old (Note II) and sell the S3 so ....
1. I assume it is likely carrier locked - right?
2. If I turn it on w/ included SIM it will a) no longer be New in Box and b) deactivate my old phone.
3. If I sell as Carrier locked, then I'm going to lose sale value.

Any suggestions or resources to sell a NEW AT&T phone and get max value?

Unlock the phone.

Unlock the phone.

Ok - but will I need to put a SIM card in and turn it on? Won't that activate my sim, change it from New to Used and change the startup process? Do I need to insert a SIM to unlock?

Just trying to figure out what is "customary."

Thanks so much for the help!

You don't need a sim to turn on. If you put a non at&t sim card, it will ask for a code

Pull out the SIM, turn it on, unlock it, then factory reset it and put it back in the box. Then sell it.

How much are you asking? I'd like to have a spare to play with.

Just listed it on Ebay a min ago. Didn't end up unlocking after all but I don't even think it is locked! : Mode Edit: Link Removed.
If you want to play with one, I'd buy it used - this is new so someone can resell overseas I guess.

But cannot buy oversea directly from you. Bummer!

Can't sell products on XDA. Please list on Swappa or Ebay.
