I know this question probably has been answered numerous times but I wanted to get a definite answer. My upgrade is next year and I have unlimited data on Verizon and I wanted to know if I can buy the 64GB iPhone 5 full price (I know the price for it) without contract extension from Apple or Verizon? Can I just walk in and purchase it from Apple or Verizon or do I need to order it? And which is the easier route going between the two?
