I'm a young professional. Which iPhone do you recommend? 5s, 5c, 4s and why?

The latest and greatest is always best. IPhone 5s is elegant looking for professional use while also providing good quality features. IPhone 5c is made for those who can't afford the best. And the 4s is small and old.

  • Would you recommend the iPhone 6 or 6s and why? I'm planning on buying a new iPhone, right now I have the iPhone 5s but was wondering which one people liked more and why before I make a decision!
  • Why is my iphone so slow? What do you recommend doing to No I'm not talking about internet speed I mean speed as in swiping photos apps and typing and such, it's such a slow reaction and freezes quite a bit, anyone know what to do or how to help, thanks.
  • Which wireless carrier you recommend below $50? I have Sprint service right now and the contract is expiring in Feb. I have iphone 4s with SIM card.So, I can switch to any GSM service too. I'm not a heavy data user (may be 500MB a month ) and use only approx. 700 minutes with text. Which wireless carrier you recommend? Suggest something below $50.
  • Which iPhone 4S case do you recommend? Right now I have a sh*tty speck case that keep ripping on the bottom and I was thinking of getting a mophie charging case but I'm not sure. I want something light and not bulky. What do you recommend?
