Will I be able to factory unlock a new AT&T iPhone 6?

I spend about half my year abroad these days and am very excited to buy the new iPhone 6 when it comes out.

I'm curious if I will be able to factory unlock it once I purchase it so I can use any SIM, anywhere in the world.

I will be buying the phone through AT&T, subsidized for $200 or whatever it is priced at. I will remain on contract with AT&T as I have been with them for 12 years now, but would like to unlock the phone immediately after purchase.

Will this be possible? Will it be costly?

Will there ever be a way to bypass the activation lock on iphone?

I'm talking about for iphone 4s ios 7.1.1
Is there ever going to be a way for people to get around it and if there's in the far future, could you tell me please?

Added (1). 1. Does every single iPhone require you to enter a apple ID activation after updating/restoring, or is there a way to bypass it and have the phone permanently unlocked from ever having to enter the apple ID after updating/restoring?

2. When the phone is accessible and working fine, how can you replace the existing apple ID on the iPhone with your own without the password of the previous apple ID?

I'm getting my first iPhone, a 5s, soon, and I'd like to know what would be the proper way to charge it. I've heard different things from different people lately: charging it on airplane mode, charging it all the way but not using any apps, etc.
