I pre-ordered two X's my wife says it's too expensive and said she doesn't want her's. I purchased both phones via apple.com on AT&T Next. I'm wondering how AT&T will handle the return? Am I now locked/forced into a contract with them since I made a purchase using Next? Or how does that work? Will they just put my bill back the way it was before (other than charging me the $$$ for my X)?
