I'm one of those people on the fence on this upgrade. I just got a refurbished 16gb iPhone 5 yesterday from the Apple store because my previous iPhone 5 was messed up and I got them to swap me out for a new one on my last day of warranty. So since this one is still so shiny I was thinking I should sell it for (hopefully) $400 and picking up the 5S at full cost (I'll end up spending an extra $200 or so after all is said and done). BUT the only things that are "WOW" factors for me on the 5S; are the new camera features and the processor speed... both of which though nice aren't MUST HAVE and my iPhone 5 works great. EDIT:I have an Upgrade currently, but I am jumping to T-mobile from At&t in December... in which case there are no "upgrades" since I'm paying the full price for the phone. I was debating just unlocking my phone once my contract is up and popping in a T-Mo card. One option I had was upgrading now with my At&t and then bail in Dec with my family and pay the ETF essentially paying $505 ($200+$325 ETF) for my upgrade. So I wanted to get some public opinions on people who upgraded from the 5 to the 5S. Should I make the jump? Yay or Nay?
