Unactivated iPhone 5 unlocking?

[RobaLonches]

First, a little backstory -
Recently, I broke my iPhone 5's screen. I had the accidental protection from Best Buy which I used to get it fixed. During the time of the repair, my family who shared to family plan with AT&T decided to switch to Tmobile. I took that opportunity to pick up a 5C. To my surprise however, Best Buy was incapable of repairing my iPhone 5 so they gave me a brand new unit. I'm still on a contract with AT&T so I was going to sell the new iPhone 5 and use that money to cancel my contract with them. With that in mind, I went ahead and asked the Geek Squad guys not to activate my phone so that it stays in the perfect and new condition. When I went to the AT&T Customer Device Unlock Request Form, I see that they ask for phone number, which is currently not on this device.

Three questions, is unlocking an unactivated iPhone 5 possible for relatively cheap? Is the resell value of an unlocked iPhone 5 really that much greater than a locked unit? If so, by how much?

Thanks in advanced for your time

When you pay the ETF for that line then AT&T will officially unlock that iPhone.
Then you wont have to pay to purchase an unlock. AT&T 3rd party unlocks currently are over $100 so very expensive.
The cheap and fast AT&T iPhone unlocks are over.

As mentioned in another post I unlocked 2 unactivated iPhone 5s the other day through AT&T. They're both showing unlocked on I MEI websites. However when I went to turn the phone on yesterday and insert an international Sim nothing happened it didn't work. I've tried to do a restore in iTunes as well as network refresh still nothing. Anyone know what the issue can be? This is the same issue on both phones

Did you ever hear anything or figure out what was wrong?
